摘要
本文在综合考虑土的粘聚力的前提下,通过对挡土墙后的滑动棱体进行受力分析,推导出了主动土压力的计算公式,并把该公式的计算结果与库仑土压力计算结果通过算例进行了比较,说明了计算土压力时综合考虑粘聚力的必要性及合理性。
This paper considers cohesion force of soil and takes an force analysis to slip prism body which is on the back of retaining wall. By this method,the active earth pressure's formula have been obtained and compared the calculated results with coulomb earth pressure theory. By that means,the paper explains the necessity and rationality of cohesion force in calculating earth pressure .
