降雨時の浸透挙動と斜面の不安定化について（その２）

Abstract

As a complementary report for the previous paper, which concerns evaluation of seepage behaviors during rainfall and their influences on instability by wetting of slopes of soil layers with uniform thickness, seepage flow analyses are additionally conducted in this paper to investigate and discuss for other various influential factors and conditions. The factors to be considered in this paper are the configuration of slopes (height and inclination of layer), the wet condition of slopes before rainfall (initial degree of saturation) and the relationship between the strength of rainfall and the permeability of soil (r/ks-ratio). The evaluation method of seepage failure at the toe of slope is revised to investigate the extension of failure in details.
