摘要
本文分析了重力式基坑支护系统可能包含的多重破坏模式后，在考虑土性参数不确定性的情况下，运用系统可靠度理论对基坑支护系统的失效概率进行分析和计算。结果表明该方法能对基坑系统的稳定性作出较全面的评价。
Firstly the paper analyzes every failure model contained in the braced system of gravity
foundation pit. Secondly it calculates the failure probability of foundation pit by application of
systematic reliability theory. Finally it takes soil parameters as uncertainty variables and the
example shows that this method can give a comprehensive judgement of the stability of
foundation pits.
