挤土桩施工过程中的挤土效应及其机理分析

Analysis on driving effect and its mechanism in construction of compacting pile

当软弱地基无法满足承载力要求时,需要对地基基础进行加固补强处理,挤土桩是一种较好的地基加固方法,但挤土桩在施工过程中会产生挤土效应,对环境造成一定的影响,文章旨在对挤土效应的影响、内在机理及防治措施做一些分析探讨并介绍了工程施工实例。

When the weak foundation was unable to meet the requirements of bearing capacity in the course of foundation engineering construction, consolidation and strengthening treatment of the groundwork foundation were necessary. Soil-compacting pile was a right method, but it would bring about driving effect during construction that would affect the surrounding environment. The authors in the text analyzed the influence and mechanism caused by the driving effect, advanced preventive measures and cited engineering construction cases.
