基坑支护设计中水土压力的计算分析

Computation of water and earth pressures on the supporting structure around a foundation pit

基坑支护设计中,水土压力计算存在着"分算"与"合算"两种方法的分歧。本文基于有效应力原理,从计算方法和水土相互作用机理方面对两种计算方法进行分析,最后推荐了一种计算水土压力的通用方法。

The method of estimating water and earth pressures on supporting structure separately and together has become an attention and discussion focus. In this paper, based on the principle of effectives stress, the method of estimating water and earth pressures is analyzed. Finally, a current method is commend on earth pressure on supporting structure of foundation pit.
