摘要

根据Biot动力理论，采用Fourier和Hankel变换方法得到了半空间饱和土受移动载荷及土体内受垂直简谐载荷作用下频域内基本解。根据虚拟桩法，得到了移动载荷作用下桩基的第2类Fredholm积分方程，并应用IFFT方法得到时间、空间域内单桩的动力响应。数值结果表明，移动荷载会引起桩身的负摩擦力；桩身最大轴力、孔压随移动荷载速度增加而增大；此外，在桩上端部会出现孔压集中现象。

Abstract

Based on Biot’s theory

the general solutions for a poroelastic half space subjected to moving loads and the fundamental solution corresponding to a vertical harmonic force applied at the interior of a saturated half space are developed via the Fourier transform and Hankel transform method. Utilizing Muki’s method

the second kind of Fredholm integral equation describing the dynamic interaction between a pile and the half space is obtained. Numerical results in the time-space domain are obtained by performing the inverse Fourier transform. Numerical results show that the moving load can generate negative frication at the side of the pile. The maximum axial force of the pile and the pore pressure along the pile side increase with increasing load velocity. In addition

the pore pressure concentration phenomena occur at the upper part of the pile.
