摘要

桩基础对邻近场地作用冲击荷载的响应本质上是桩-土组成的体系在冲击荷载下的整体动力相互作用问题。为了研究该问题，采用有限元法模拟冲击荷载引起桩基础的振动。利用通用有限元分析软件ABAQUS建立了有限元-无限元（FE-IFE）耦合分析模型，分析了冲击荷载作用时桩基础动力响应的规律，并对影响桩基础响应的因素进行了探讨。计算结果表明，桩的振动程度取决于冲击荷载作用间距和冲击荷载能量，而冲击荷载作用间距越远，桩的振动波长越长。

Abstract

The problem of pile foundation response to impact loading on adjacent field is a dynamic interaction of the whole system consisting of piles and soil under the impact load. To study the potential vibration of the pile foundation affected by impact loading on adjacent field

the vibration is simulated with finite element method (FEM). Using FEM software of ABAQUS a coupled finite element-infinite element (FE-IFE) model is created; the pile foundation response to impact loading on adjacent field is analyzed; then the factors affected pile foundation response are considered; some useful conclusions are drawn; the value of vibration amplitude is determined by energy of impact loading and distance between pile foundation and impact site; and the wavelength of pile foundation vibration is determined by distance between pile foundation and impact site.
