摘要
PHC管桩通常为挤土沉桩模式,因而沉桩过程中的挤土效应研究对设计、施工具有重要意义。通过对PHC管桩打桩前后原位地基土变化情况的测试、打桩的监测以及孔隙水压力增长与消散的监测等试验研究,分析了PHC管桩沉桩挤土效应,为工程设计及施工提供可借鉴的依据。
Experimental research on compacting effect of PHC piles is significant to design and construction.To analyse the compacting effect, credible reference for engineering design and construction is provided by the aid of the test result, such as the parameter changes of in-situ foundation, the observation of piles construction and the measure of pore water pressure.
