Efficiency of the Monte Carlo Simulation Method in Evaluation of Liquefaction Potential

Abstract

Reliability analysis is a useful and comprehensive approach for estimation of liquefaction potential in soil layers. The most commonly used methods in reliability analysis are first order second moment (FOSM) and Hasofer&Lind approaches. These methods are based on some simplified assumptions such as the use of a linear performance function or the numerical estimation which often lead to less accurate results. Monte Carlo simulation (MCS) approach is an alternative and more accurate method for reliability analysis and for evaluation of liquefaction potential in soil deposits. In this study, liquefaction potential is assessed using MCS approach followed by a case study in which an area prone to liquefaction is investigated. Results are compared with those obtained by other reliability methods. The efficiency of the MCS method is discussed in the paper.
