Liquefaction Potential Analysis and Numerical Modeling - Container Terminal of Algiers Port

Abstract

The aim of the present paper is to study the liquefaction potential of the container terminal of Algiers port site and perform a numerical modeling of its dynamic response under Boumerdes earthquake. The soil liquefaction potential was analyzed using two methods. The first is an analytical method requiring a series of observations and empirical correlations carried out from in situ investigations, namely the SPT (Standard Penetration Test). In addition, the liquefaction safety factor obtained was verified according to the recommendations of the Eurocode rules and the Algerian earthquake regulation. The MSF coefficient was determined to obtain a corrected CSR value corresponding to a seismic motion with magnitude of 7 on the Richter scale. The second analysis is carried out using PLAXIS 2D (version 2016) software using soil parameters determined from standard triaxial and œdometric tests. The numerical modeling was established in order to study dynamic response and verify the liquefaction potential of Algiers port under Boumerdes earthquake taking into account the presence of the container static load.
