| Abstract: | 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. |
