Analysis of Reliability Calculation and System Analysis of Gravity Retaining Walls

Abstract:

The reliability indexes of the two unstable modes of the gravity retaining walls were calculated by the first-order second-moment theory through setting up the fundamental model. Results evaluated are compared with the results which is evaluate by the safety factor method, and it shows that there is still a certain degree of probability of failure of gravity retaining walls , even though they meet the checking conditions of "Safety Factor" method .The analysis shows that the failure probability of sliding stability is approximately equal to the failure probability of the entire system stability. And the stability of sliding of the gravity retaining walls should be payed more attention during the process of design checking calculation.
