    Language:Japanese   Publisher:Japan Society on Water Environment  

    Micropollutants contained in leachates from the Nonthaburi open dump site in Thailand were investigated. The leachate contained as high as 5 mg · l-1 of bisphenol A and 0.06 mg · l-1 of toluene, while the concentrations of these compounds in the leachate from the Nakornpatom engineered landfill adjacent to the Nonthaburi site were between 1/100 and 1/1000 of those in the Nonthaburi site. It is suggested that the heat generated by the biodegradation of wastes promoted the release of the micropollutants from plastic wastes in the solid waste disposal site.

    Pressuremeter tests were conducted on a model SCP ground in a centrifuge to investigate the effects of replacement ratio and coefficients of subgrade reaction of SCP. Cone penetration test using a triaxial device were conducted to examine the relationships among cone penetration resistances and confining pressure and relative density and diameter of specimen. Cone penetration test in SCP ground were analyzed using a cavity expansion theory that was expanded to SCP ground condition. By this research, it has become clear that there is a close connection between surface friction and ultimate cavity expansion pressure.

  • EFFECTS OF FOOTING SIZE AND ASPECT RATIO ON THE BEARING CAPACITY OF SAND SUBJECTED TO ECCENTRIC LOADING

    Language:English  

    The current practice of estimating bearing capacity usually employs the conventional bearing capacity formula originally developed for strip footings under vertical central loading. In order to account for the effect of footing shape and eccentricity and inclination of loads, correction factors are introduced in the formula, which are derived based on a number of small-scale model test observations. This paper describes research on the bearing capacity of rectangular footings on sand subjected to vertical eccentric loading. Two aspects, namely the effects of footing size and of footing shape on the bearing capacity and deformation characteristics, are focused on. A series of loading tests was conducted in a centrifuge on rectangular footings with aspect ratios from 1 to 5, at two different centrifugal accelerations. In addition, finite element analyses were performed in which factors influencing the angle of shear resistance including stress level dependency, anisotropy and coefficient of intermediate principal stress, were taken into account. It was found that the shape factor of footing apparently increased with increasing footing width. This indicates that the shape factor used in the current practice underestimates bearing capacity of footings. This was also the case for failure locus in the M/B-V (moment-vertical) load plane. Normalized failure locus for wider footings with a smaller aspect ratio is considerably larger than that reported in the literature. The stress level dependency of the angle of shear resistance appeared to be responsible for the scale effects of footings on the failure locus.

    In this study, using Winklerian model, five different companies made attempts to predict the performance of braced wall excavation with floating type earth retaining wall in a model site For one location, three different type of predictions were carried out without any observed data, Type A, with observed data until the second stage excavation, Type B, and with all observed date, Type C. Type D prediction was also done for the other location using the input parameters derived in the Type C prediction. By comparing the results of these predictions with the observation, discussed were effects of input soil parameters on the prediction and validity of various conditions assumed in the current design methods using Winklerian model.

    In this study, column tests were carried out to measure the coefficients of molecular diffusion of high plastic kaolin clay with different void ratios and numerical analyses were conducted to estimate the accuracy of the measured dispersion coefficients. The result of column tests showed that hydrodynamic dispersion in the clay was mainly caused by the molecular diffusion and the trend between the void ratio and the dispersion coefficients was similar to that between void ratio and hydraulic conductivity. From the numerical analyses, it was found that the precision of measurement of dispersion coefficients depended on the vertical distributions of physical properties of clay sample and the accuracy of the initial and boundary condition in column tests.

    In designing structures, especially harbor structures on soft clayey ground, deformation of the foundation ground may sometimes appear as a vital factor for rational design. Both the short and long term behavior of soft clay improved by sand compaction piles with low replacement ratios, which is subjected to backfilled caisson loading, were investigated through a series of centrifuge model tests. In model tests, the construction sequence from the installation of the caisson to backfilling was simulated in-flight. Effects of replacement ratio, improvement width, SCP location and loading rate on the behavior of the caisson were studied. It was found that settlement of the model ground can be effectively reduced by a higher replacement ratio, and long term settlement of caisson after backfilling is highly influenced by the settlement of the ground behind the SCP portion. A wider improvement area towards the fill is more effective in reducing the lateral displacement of the caisson both during and after backfilling, and the degree of consolidation of the clay part in SCP ground has a significant effect on short term lateral deformation.

    In order to obtain p-y curves of single pile in sandy ground, a divided pile loading system has been developed. The p-y curves can be directly measured from small to large displacement with this system. A series of centrifuge model tests has been conducted to investigate the effect of depth and diameter of piles on the p-y curves. It was found that the p-y curves can be modeled by hyperbolic curves with initial gradient of subgrade reaction kh and ultimate subgrade reaction pmax. An attempt was also made to simulate the behavior of horizontally loaded single pile by p-y curves obtained from the divided pile loading test.

    There had been very few records on damages of steel pile type piers in previous earthquakes. However, several piers located in front of gravity caissons were damaged during the 1995 Hyogoken-Nambu Earthquake. Damage of piles at the site suggested that the lateral flow of the ground might accelerate the failure of the pier. In this study, centrifuge tests were firstly carried out to simulate dynamic behavior and failure of a steel pile type pier damaged in 1995 Hyogoken-Nambu Earthquake. And also some tests with different ground conditions were conducted to discuss the effects of liquefaction of the sand layer under the rubble mound on the lateral flow of the ground and the effect of the approaching plate connecting gravity caisson to ther pier on the dynamic interaction between the two structures.

    Centrifuge model tests were conducted to study the behavior of geogrid reinforced embankment during earthquakes. In this study, an attempt was made to discuss the effects of length and spacing of geogrids on the behavior of the reinforced embankment. It was found that displacement of reinforced zone was caused by the combination of sliding and shear deformation of the zone. The larger sliding took place in the case with the short geogrid for reinforcement irrespective with the placing. Spacing of geogrid mainly affected the shearing deformation.

    A dense sand layer is usually assumed to be a bearing stratum in foundation design. It is, however, difficult for engineers to judge if a sand layer with limited thickness can be used as a bearing stratum when it is underlain by a thick soft clay deposit. Many important parameters must be considered in this problem, for example, the thickness of the sand, strength of clay and width, shape and embedment of footing. Several methods have been proposed to calculate the bearing capacities of the sand overlying clay, in which limit equilibrium of forces acting on an imaginary sand block between the base of the footing and the sand/clay interface was considered. The bearing capacities calculated based on existing methods are not the same for different assumptions adopted in each method. The shape of the sand block and the forces acting on the surface of the block are the determining factors in the bearing capacity calculation. In this paper, these factors as well as calculated bearing capacities are compared with the results of well-conditioned centrifuge tests (Okamura et al., 1997) to verify the validity of the methods. It has been confirmed that reasonable assumptions in which the variation of the shape of the sand block and the forces related to the parameters are taken into consideration are important to obtain a reasonable prediction. An alternative method is proposed and the bearing capacity charts are presented for easy reference.

  • Long term behavior of Piled bridge abutments in soft clay subjected to backfill loading

    When embankment is constructed behind a piled bridge abutment in soft clay deposits, lateral deformation of the clay caused by the fill loading may lead severe damages of the pile foundations. After completion of the backfill, however, ground deformation occurs due to undrained creep and consolidation, and these phenomena may affect the stability of piled structures. In this paper, a series of centrifuge tests were conducted to investigate the long-term behavior. An attempt using FEM with modified Cam-clay model for clay was also made to predict it. From these results, the effects of some influence factors as depth of soft clay and pile tip fixity conditions to the long term behavior were studied.

    A series of centrifuge model loading tests on dense sand overlying soft clay was carried out to investigate its bearing capacity and associated deformation including the failure mechanism. The effects of the thickness of sand, the strength of underlying clay and the width, shape and embedment of footings on the bearing behavior of the sand were studied. It was found that the bearing capacity increases with increasing sand thickness-footing width ratio until it reaches that of uniform sand, which can be considered as the upper limit of the bearing capacity of the layered soil. The bearing capacity also increases linearly with both the strength of the clay and the overburden pressure at the footing base. For cases with bearing capacity smaller than that for uniform sand, punching shear takes place, where a truncated cone shaped sand block between the footing base and the clay surface penetrates into the clay. The side angle of the sand block to the vertical increases with increasing sand thickness-footing width ratio and overburden pressure, and decreasing clay strength. It was confirmed that this variation of the angle should be taken into account in the bearing capacity calculation.

    A series of centrifuge model tests were conducted to investigate the influence of the size, shape and the depth of embedment of footings, and the ratio of grain size to footing breadth on the bearing capacity of dense sand. Strip and circular model footings were used in the tests. Bearing capacity analyses were also carried out by solving the Kötter's equations in which the stress dependency and anisotropy of the internal friction angle φ′ were taken into account. It is found that the effect of the ratio of grain size is negligible for circular footings, while for strip footings the ratio has a substantial effect. The calculated bearing capacities are in reasonable agreement with the tests results. It is confirmed that the scale effect of shallow footings on the bearing capacities are mainly caused by stress dependency of φ′.
