小型桩基础下压承载特性模型试验方法探究

Discussion on Model Test Method of Vertical Bearing Behavior of Small Pile Foundation

针对传统的桩基模型试验装置存在的缺陷,根据模型试验原理,设计了一种新的模型试验装置和试验方法,能够有效和精确地测得桩顶竖向位移随竖向下压荷载的变化,从而得到桩抗压承载特性,指出新的装置与方法制作简单、加载简捷、模型桩受荷稳定、具有一定的扩展性,应用前景广阔。

In view of the defects of traditional pile foundation model test device,a new test device and the test method are designed according to the principle of model test,which can effectively and accurately measure vertical load change and get the bearing capacity of pile.The test method is simple and expandable,and it has a wide application prospect.
