考虑空间效应和土体粘聚力的短墙土压力分析

Earth pressure analysis on short retaining wall considering spatial effect and soil cohesion

由于一些挡土结构的长高比较小,墙后土体两侧受到约束。对该类短墙上土压力的空间效应进行分析,考虑了土体的粘聚力和土与挡墙之间的粘着力。通过分析说明,土体空间约束后,土压力远小于经典的平面土压力,有利于短挡土墙的经济合理设计。

Some retaining walls have small ratio of length to height. For this type of short retaining wall soil behind the wall is under restraint at two sides, so spatial effect of earth pressure is analyzed, considering soil cohesion and adhesion between soil and wall. When soil spatial restraint is considered, earth pressure is far less than planar earth pressure, which is economical to the retaining wall design.
