软土地基上静力压桩若干问题的分析

预制桩采用静力压桩法在软土地区已越来越被广泛采用，甚至应用在２０层以上的高层建筑也已有数十例。但这些成就更多的是依赖于施工单位的经验取得的。现有的规范已经不能满足生产实践的需要。作者总结了所见的研究成果，对软土地区静力压桩的若干问题进行了分析与研究。建议尽早进行有关的专门规范研究与制定工作。

Analysis of Some Problems of Statically Pressed Piles in Soft Soils

Statically pressed piles have been more and more widely adopted to support building in soft soil areas,some highrise ones being over 20 storeys.However,in many cases this kind of operation is mainly dependent on the experiences and achievements of construction companies whereas existing codes do not meet the needs of such engineering practice.This paper reviews the previous research works on statically pressed piles and analyzes some problems in application.Finally,sug gestion of revising the code for statically pressed piles as early as possible has been proposed.
