摘要： 在基坑支护设计中，土压力的计算是基坑支护设计过程中最为重要的环节，而土体的抗剪强度参数又是土压力计算过程中最基本的参数，所以选取合理的抗剪强度参数是深基坑工程设计的关键。鉴于此，以某深基坑工程为例，对该基坑各岩土层的抗剪强度参数分别采用了三种方法（规范法、最小二乘法、MATLAB多元线性）进行数理统计分析和对比，最终优选出各岩土层的最佳的抗剪强度参数。

Abstract: The horizontal earth pressure estimation is the most important procedure in the deep excavation support design, whereas, the shear strength parameters are the basic parameters for the lateral earth pressure estimation. Therefore, selection of appropriate shear strength parameters are the critical step for the deep excavation supporting system design. In this paper, three shear strength selection methods are used for a deep excavation supporting design project: Code Method, Least Square Method and Multiple Variable Linear Method using MATLAB. Statistical methods are used to analyze these parameters and the shear strength parameters are able to optimize.
