A bearing capacity analysis was carried out for a highly structured naturally deposited clay ground using the soil-water coupled finite deformation analysis code GEOASIA, which takes inertial forces into consideration and employs the SYS Cam-clay model, which is capable of describing the work of the soil skeleton structure. The following results and conclusions were obtained. 1) When a ground that exhibited localization of deformation and formation of a circular slip failure accompanied by load reduction as a result of loading by displacement control was loaded by load control, it failed dynamically in association with acceleration motions after reaching the peak load obtained during displacement control. To date, the bearing capacity problem has only been dealt with quasi-statically, but it is essential to take inertial forces into consideration in order to reproduce this type of failure behavior. 2) Using the analysis code, it was possible to reproduce the behavior before, during, and after the delayed failure phenomenon, as well as whether or not there is a load threshold for occurrence of delayed failure. To reproduce this type of phenomenon, a time-dependent constitutive equation is not necessarily required.
