静力压桩挤土效应中的若干力学问题

在饱和软粘土中进行静力压桩所产生的挤土效应会对工程环境（桩周土、周围建筑物和构筑物）产生相当严重的影响，早在五十年代人们就开始研究这一问题，由于该问题的复杂性，至今仍然没有获得满意的结果。本文首先分析总结了前人的研究方法和成果，然后就该问题所涉及的几个力学问题进行了较详细的分析，同时提出进一步研究这一问题的合理方法。

SEVERAL MECHANICAL PROBLEMS IN COMPACTING EFFECTS OF STATIC PILING IN SOFT CLAY GROUND

The compacting effects caused by static piling in saturated soft clay ground may have severe influence on engineering environment (the driven soils around the pile and the near buildings). The research history dates back to the early 1950's. However, no satisfactory results have been obtained because of the complexities of the problem. In this paper, a brief summary of the methods and conclusions reached by former researchers is presented. Several mechanical problems conceding the compacting effect are studied in detail. Appropriate methods for further studying are proposed
