摘　　要：文章建立了桩土模型,把桩身当作Bernoulli-Euler梁,桩周土当作Winkler地基,研究桩顶受到横向冲击荷载时桩的瞬态横向动力响应;应用有限差分法得到桩身各点响应的数值解;分析桩长、桩周土剪切波速和桩顶横向激振力作用时间对桩的瞬态横向动力响应的影响。This paper establishes the pile-soil model, in which the pile is assumed to be a Bernoulli-Euler beam of finite length, and the soil around the pile is treated as Winkler foundation. The transient lateral response of the pile subjected to the lateral impulse load at the pile head is studied. The response of each point of the pile is obtained using the finite difference method. The effects of the pile length, the velocity Of shear wave of the soil and the duration of the lateral impulse load at the pile head on the transient lateral dynamic response are investigated.
