Abstract

To simulate the behaviour of saturated sands under cyclic loading, the PM4Sand constitutive model (version 3.1) formulated by Boulanger & Ziotopoulou [1], is used. The model can realistically reproduce the pore pressure build-up, accumulation of strain as well as triggering of liquefaction. The effect of dif-ferent relative densities on liquefaction resistance is evaluated by comparing the results of a site response analysis performed on a soil column character-ized by a saturated sand layer and subjected to given earthquake signals. The analyses are performed using the finite element code PLAXIS.
