Abstract
Based on the numerical analysis of transient longitudinal vibration model of an integrate pile,it is found that parameters of soil,pile and impact force have effects on dynamic response of the pile.When the pile is free, the ratio of incident wave maximum value to reflection wave maximum value is two.When the pile is in the ground, the ratio decreases with the increase in the shear modulus of soil around the pile, the pile length and the impact time,and the ratio increases with the increase in the diameter and elastic modulus of the pile. The phases of incident wave and reflection wave are the same or opposite when the ratio of the shear modulus of soil under the pile toe to the elastic modulus of the pile is less than 0.01 or more than 0.10.
