長大斜面の三次元すべり破壊特性に関する遠心模型実験

Abstract

Centrifuge model tests were performed in this study in order to investigate how three-dimensional sliding failures take place in high earthfills with long slopes. The spherical sliding planes were meseaured by using noodle-type reference strings embedded in the model, and the length, the width and the depth of the sliding bodies were compared by varing the width of valley in which earthfills are constructed. By using the measured sliding body, the difference between the three- and two-dimensional factors of safety was examined by using the conventional slice method.
