中文摘要：
采用Muki虚拟桩法,在频域内建立了移动荷载作用下饱和土体—桩系统相互作用的第二类Fred-holm积分方程,通过离散积分方程与傅里叶逆变换,得到了时间、空间域内桩—土的动力响应,并通过数值计算,分析结果表明：当荷载速度较高时,桩侧有明显的负摩阻力,同时桩顶上部有较大的负孔压.
英文摘要：
Utilizing Muki＇s method,the second kind of Fredholm integral equation describing the dynamic interaction between the pile and the half-space subjected to moving loads is obtained in the frequency domain.After performing the inverse Fourier transform on the frequency domain solution,the dynamic response of a pile embedded in a poroelastic half-space to a moving load in the time-space domain is investigated.Numerical results show that the moving load will cause negative friction along the pile side.Also,the maximum pore pressure usually occurs around the upper part of the pile.
