关于基坑支护结构土压力计算的若干意见

Some opinion on the earth presure computing of the fender structures onthe excavation engineering

本文根据有效应力原理、土的渗透性与孔隙水传递静水压力的条件,基坑支护结构与挡土墙的差异,以及基坑支护结构工作性状的工程监测结果,对基坑支护结构的土压力计算问题进行了讨论,并提出了依据Rankine土压力公式计算土压力的具体处理方法。

Based on the principle of effective stress, permeability of soils,the condition of transitive hydrostatic pressure of pore water in soils,the influence of soil deformation on earth pressure of fender structures in excavation engineering, the difference between the fender structure and the retaining soil wall,and the results of site measure on the working characteristics of the fender structures,this paper discusses the problem of earth pressure computing of the fender structures,and presentes a specific method of earth pressure computing for the fender structures based on the Rankine's theory.
