等体积原理在挤土桩施工中引起地基土体变形的应用

摘要

针对挤土桩基施工时引起周围土体变形问题，采用挤土量与排土量体积相等的原理和工程实例相结合的方法，着重分析了土体变形规律，研究结果可为同类工程的设计与施工提供依据，也可对桩基设计与监测提供参考。%According to surrounding soil deformation in compaction soil pile foundation construction,using the soil compaction and soil volume equal principle and engineering examples combining method emphatically analyzed the soil deformation law,the results could provide basis for similar engineering design and construction,but also provided reference for pile foundation design and monitoring.
