Abstract

Liquefaction is a phenomenon which is related to sudden dramatic reduction of the bearing capacity of a soil under the effect resulting from intense and fast seismic or any other dynamic loading. Liquefaction occurs generally in saturated soil. This phenomenon is of considerable importance because of the destructive impact that can provoke on civil engineering infrastructures, economy and human life. Classical works studying the problem of soil liquefaction include many empirical approaches such as theĀ  deformation approach, the stress approach and the energy approach, were the liquefaction resistance is usually assessed using methods and procedures developed based on field tests. The standard penetration test and the cone penetration test are two tests that are widely used to analyse the potential of soil liquefaction. These tests are deemed reliable and permit to estimate the soil liquefaction potential. The correlation formulas depend however on the site where they were established. To adapt them to another site such as soils existing in the northern Moroccan city of Tangier requires a further investigation study. The semi-empirical Juang approach was found to be more suited to predict the liquefaction potential of soils found in the region of Tangier. In this work predictions of Juang method are compared d to those obtained with a rigorous two-dimensional physical modelling where DeepSoil software was used to develop the numerical model.
