基坑支护及挡土墙设计中土层拱效应的理论分析

The Theoretical Analysis on the Soil-layer's Arch Effect in the Design of the Foundation Ditch Supporting and the Earth-retaining Wall

通过对水平土拱形梁法的分析,得出了支护桩之间的合理间距,为工程人员设计应用提供了可以量化的理论依据,并提出在支护设计中应采用强桩弱墙的支护结构。

Through the analysis on the horizontal soil arch beam, this paper obtains the rational space length between the supporting piles, which provides quantizationable theoretical basis for the design application of the technicians, and puts forward that in the supporting design the supporting structure of stronger pile and weaker wall should be adopted.
