沉桩问题的光弹性模拟研究

The Simulated Study of Pile Driving by Photoelastic Method

实现了桩身直接贯入的沉桩光弹性模拟方法。应用这一方法研究了沉桩过程中桩周土体中的弹性应力场及其影响区域。

In this paper,a photoelastic simulating method of pile driving is presented.The elastic stress field and its influence zone of soil around the pile are studied by this method.The suitable scope of Vesic's theory on the expansion of a cylindrical cavity is also pointed out.
