砂質地山に打設された地すべり抑止杭の数値解析

Abstract

Walls of piles have often been used as a stabilizing device for landslides. Sincethe issue of how to stabilize the effect of landslides by the piles is an importantone, a series of two-dimensional laboratory model tests have been carried out tohelp elucidate the preventive mechanism of these piles. In this study, the results ofelastic-perfect-plastic finite element analyses, and elastic finite element analysesincluding joint elements are compared with those of model tests, taking notice ofthe deformed condition of the ground surrouding the piles and of the lateral earthpressure acting on the piles.
