摘要

根据上海某软土工程试验资料，对比分析了不同试验方法抗剪强度指标计算基坑土压力的变化。参考国家标准、行业标准和地方规范，同时结合实际工程经验和地方经验，论证了不同试验方法抗剪强度指标的适用性。建议在基坑支护结构设计中土压力计算应采用固结不排水强度指标，当有可靠工程经验时，也可采用直剪固快强度指标。

Abstract

According to the experimental data in soft soil foundation pit in Shanghai

this paper presents the variation of calculating earth pressure based on the different shear strength parameters. Considering national codes

technical specifications and local code

combined with the practical and local experiences

the applicability of different shear strength parameters are analyzed. In the design of supporting structure for foundation pit

this paper suggests that shear strength parameters of consolidated undrained experiment should be used to calculate earth pressure; and that shear strength parameters of consolidated quick direct shear test may be used to calculate earth pressure when with credible experiences.
