Abstract In this paper，a model of tubular piles with variable section is proposed to simultaneously investigate the three-dimensional effect of variable section and the damping effect of tubular piles on the dynamic response. The analytical solution of the dynamic response is derived in Laplace domain，and its semi-analytical solution in time domain is obtained by inverse Fourier transform. A parametric study of the static drill rooted method and the pile structure is conducted. In order to emphasize the structure information of piles，the parameters of static drill rooted method should be restricted for the dynamic test，according to pile?s inside diameter and nodular segments? outside diameter，height and interval. On this basis，some conclusions are summarized to provide a practical guidance for engineering implementation.

Key words： foundation engineering static drill rooted nodular pile variable section tubular pile dynamic test integral transform
