摘　　要：基于上海地区地下空间开发的地质分区等研究成果,分析了不同地质组合存在的变异性,并对不同地质组合条件导致的基坑围护体系可能存在的失效风险做了初步定量分析,获得了地质条件变异性引起的基坑失效概率,并进行了统一比较。定量分析的结果反映的规律与常规工程经验非常一致。Based on the geological studies on underground development in Shanghai, the influence of soil varidity on foundation ecxcavation were discussed. The risks caused by soil varidity was also analyzed by mathematical method. The probability was also calculated under different geological conditions. The results were found to agree well with the engineering experiences.
