摘要
结合常规定值计算方法，提出用于软土基坑水泥土挡墙可靠度分析的6种失效模式。建立了相应的极限状态方程．在具有代表性的18例上海软土地质资料基础上，参数统计采用空间平均特性概念，用一次二阶矩验算点法（JC法）进行有关的可靠度计算与分析，分析结果与工程实践基本一致。
In this paper, referred to conventional deterministic design methods, 6 failure modes used to analyse reliability on cement - soil retaining wall of excavation in soft soil are proposed. Based on 18 different and representative geotechnical data in Shanghai and the application of the concept of spatial aveage JC - method is used to calculate and analyse the reliability indices on cement - soil retaining wall at different excavation depth. Conclusions obtained coincide with the engineering experience, and will be helpful for the future researeh work of partial factors of c and Φin the design of cement - soil retaining wall in Shanghai area.
