• NUMERICAL LIMIT ANALYSES ON THE BEARING CAPACITY CONSIDERING THE LOCALITY OF LIQUEFACTION AND SEISMIC LOADING

抄録

In this paper, the locality of liquefaction in stabilized ground is expressed on the random theory and the bearing capacity under seismic loading is analyzed through Monte Carlo Simulation with Numerical Limit Analysis. The purpose of this paper is to clarify the effects of local liquefaction in ground and the pattern of liquefaction on the bearing capacity factor under seismic loading. As a result of this analysis, following conclusions were obtained. (1) The distribution of bearing capacity factor under seismic loading considering the locality of liquefaction can be expressed by log-normal function. (2) The bearing capacity factor under seismic loading decreases with the increasing the area of local liquefaction in ground and horizontal seismic coefficient. The liquefaction ground has no clear slip surface and comes to destruction with a little deformation. (3) The bearing capacity factor under seismic loading and the failure mode against seismic loading depend on the pattern of local liquefaction.
