Abstract

To study the application of the moment method in gravity retaining walls, this paper established functional functions for the anti-sliding and anti-overturning limit states of gravity retaining wall structures, and developed a reliability analysis method based on the third-order moment method for a single failure mode. The analysis results show that compared with Monte Carlo simulation method (MCS) and first-order second-order moment method (FOSM), employing the moment method for stability and reliability analysis of retaining walls can both improve calculation efficiency, ensure calculation accuracy, and obtain the first three-order statistical moments of the functional function. Then, based on the moment method, sensitivity analysis was conducted between the reliability index and design parameters of the retaining wall structures. Finally, the sub-coefficients of the anti-sliding and anti-overturning limit state equations were obtained based on the moment method. Compared with the sub-coefficients obtained by the other two methods, the third-order moment method is a fast and efficient reliability calculation method.
