ANIMATED SIMULATION OF PILE-DRIVING PROCESS

本文通过三维显式有限元计算结果，对混凝土桩打入地基的过程进行了三维动力反应分析，并完成了此过程的动画仿真研究，研制成可携带的录相带式的仿真动画，形象、生动、直观地再现了桩贯入地基过程中撞击波在桩体、地基中的传播，桩体与地基间的相对接触、滑移及桩锤与桩头部间的接触撞击过程．

In this paper three-dimensional dynamic response analysis and animated simulation for driving process of concrete pile have been completed by results of explicit element analysis. Animation tape, which is easy to carry, is developed. Impact wave propagation along pile and ground in pile-driving process, opposite contact, sliding betwee n pile and ground, and contact impact process between hammer and pile top are figuratively,lively and directly reproduced.
