静压桩挤土效应问题的研究

在饱和软粘土中静力压桩会产生严重的挤土效应，它对桩周土体、周围建筑物和其他工程环境将产生严重的不良影响－ 这一问题早已引起了人们的关注，最早的研究始于５０ 年代，至今这一问题仍然是一研究热点－ 由于该问题非常复杂，涉及到多方面的基本问题，虽然已有很多学者采用不同的方法对该问题进行了研究，但仍然没有获得满意的结果－ 通过简要分析前人主要的研究方法和成果并指出其局限所在，然后提出进一步开展该项研究所应注意的问题

A Study on Compacting Effects of Static Piling in Soft Clay Ground

The compacting effects caused by static piling in saturated soft clay ground would bring severe negative influence to the construction environment including soils around the driven piles ,the nearby buildings and so on. In the early 1950's , the studying of this problem was started .Today, the problem is still a researching hotspot. The problem is very complicated because a lot of basic problems are involved. Although different methods have been adopted by many researchers, no satisfactory results have been obtained until today. In this paper, a brief summary of the methods adopted by former researchers is given,including their contributions and limitations. Then several aspects which should be noticed for further research are put forward.
