Abstract

This paper proposes an efficient reliability-based design (RBD) updating procedure for geotechnical structures, which integrates the Expanded RBD method based on Monte Carlo Simulation (MCS) with a sample reweighting approach. Within the proposed procedure, the Expanded RBD is utilized to perform the preliminary design, which can obtain the failure probability (P_f) for all designs using a single MCS run rather than trial-and-error procedure. During the updating process, P_f under different design scenarios can be expressed as a weighted sum of failure sample values using sample reweighting approach. Equations are derived for integrating Expanded RBD with sample reweighting approach to evaluate P_f of geotechnical structures. The flow chart of the proposed procedure is presented and illustrated through rock slope design example. The results are validated against those from direct MCS runs.It is shown that sample reweighting can evaluate the P_f accurately and the computational efficiency is improved significantly compared with direct MCS. With the aid of sample reweighting approach, design updating can be realized effectively and efficiently using the proposed procedure.
