Validation and Verification of Semi-Empirical Methods for Evaluating Liquefaction Using Finite Element Method

Abstract

Abstract. Liquefaction is a hazardous and temporary phenomenon by which a soil saturated with water loses some or all of its resistance. The undrained conditions and a cyclic load increase the pores water pressure inside the soil and therefore a reduction of the effective stress.Nowadays many semi-empirical methods are used to introduce a proposition to evaluate the liquefaction's potential using the in-situ test results. The objective of this paper is to study their ability to correctly predict the liquefaction potential by modelling our case using finite element methods. Apart from the previous empirical analysis to evaluate the liquefaction potential, numerical modelling is performed in this study.
