- Abstract
- A series of dynamic centrifuge tests was conducted, with different pile diameters installed in dry and loose saturated sand deposit (liquefiable sand), for various conditions of input acceleration and upper mass. The test results revealed that the inertial force generated by the superstructure and the kinematic force generated by the soil movement were out-of-phase, and acted in opposite directions regardless of the ground condition. Based on the experimental results, an evaluation method for quantitatively calculating the kinematic force acting on a pile foundation was suggested using the inertial force of a trapezoidal soil wedge component. The method for predicting dynamic pile behavior considering kinematic effects was suggested by using the kinematic force evaluating method. The proposed method predicted the dynamic pile behavior better than the existing method.
