Evaluation of Dynamic Earth Pressure acting on Piles in Liquefiable Soils Using 1g shaking table tests

Abstract

In this research, the dynamic earth pressure acting on piles in liquefiable soils was evaluated using 1g shaking table tests. The magnitude and distribution of the pile displacements were analyzed with various pile diameters and concentrated mass. The earth pressure acting on piles were also evaluated with depth and pile diameters in liquefiable soil. Moreover, the dynamic earth pressure acting on piles was analyzed for various concentrated mass and compared with ground displacement. It was also compared that the kinematic effect and Inertial effect qualitatively. The westergaard solution which can calculate the fluctuating component of the dynamic water force acting on quay wall was verified as a analytic method to evaluate the dynamic earth pressure acting on piles in liquefiable soils.
