【Abstract】In order to study the influence of the lateral expansion of liquefied soil on the dynamic response of pile group foundation, a small-scale shaking table model test was designed for the influence of flow deformation of the liquefied site on the pile foundation seismic response. By using the “steel strip method”, the lateral displacement of soils in different types of sites was estimated. The correlation between the lateral flow rate of the foundation soil and the seismic internal force of the pile foundation was discussed. The influence of the inertial force and site type on the internal force reaction of the pile body was compared and analyzed, and the pile group migration resulted from the lateral expansion in the sloping site was analyzed. The test results showed that the lateral expansion of the soil around the pile and the downstream soil gradually increased from bottom to top along the depth direction. The effect of soil liquefaction and sliding on soil pore pressure dissipation can be promoted. The lateral displacement pattern of horizontal site was linear, while the distribution pattern of lateral displacement along the depth of sloping site was parabolic. The liquefaction of foundation soil weakened the lateral constraint of soil on pile group foundation, resulting in the decrease of the displacement amplitude of pile groups after liquefaction.
