Moment Methods for Assessing the Probability of Serviceability Failure in Braced Excavations
When the performance function (or limit state) is a numerical model without an explicit form, reliability analysis based on this limit state is often difficult to perform. In this paper, a series of moment methods that is built on the solutions obtained from PlaxisTM, a commercially available finite element code, is adopted for probabilistic evaluation of serviceability failure in a braced excavation. The accuracy of the computed reliability index and probability of failure tends to increase when the higher-order moments are considered. In addition, the effect of spatial variability of soil parameters on the computed probability of serviceability failure is investigated. A well documented case history of a braced excavation in clay is analyzed, and the results show that the moment methods are effective and easy to apply for computing failure probability.
