摘要
本文以具体基坑工程为依托,取现场粉质黏土原状土样,针对水、试验方法两种抗剪强度指标影响因素进行室内试验,利用不同试验组所得强度参数值计算土压力,分析不同影响因素下试验所得抗剪强度指标的差异,并指出在基坑支护结构设计中土压力计算应选取何种强度指标更为合理.
In this paper, relying on a specific excavation, by taking the scene undisturbed silty clay soil samples,laboratory tests carried out three factors of shear strength index of water, testing methods, stress state, the resulting intensity using different parameter values calculated soil test group pressure,analyze the differences under different experimental factors resulting shear strength index,,point out that the structural design in excavation earth pressure calculation should select what strength index is more reasonable.
