Abstract:
Liquefaction is accompanied by large lateral displacement, increasing excess pore water pressure and noticeable strains in soils. Soil excitation due to external loading is as vital parameter as soil inherent characteristics in the liquefaction. In order to investigate the effect of soil permeability in conjunction with loading parameters on the liquefaction occurrence in sandy soils, a numerical parametric study has been done. It is shown that soil permeability and the amplitude of cyclic acceleration are main component on the liquefaction, while the number of cycles has no effect.
