软土地区静压沉桩易产生很高的超孔隙水压力,造成挤土效应,对周围工程环境产生一定影响.从理论研究和试验研究2个方面对静压桩挤土效应研究成果进行了综述和分析,指出了当前静压沉桩挤土效应研究所存在的问题,并对其研究方法和减轻挤土效应的处治措施等方面给出了一些建议.
The higher pore water pressure will take place during jacked pile driving in soft soil area, which will cause compaction effect and affect the surrounding engineering environment. In this paper, we reviewed and analyzed the compaction effect of jacked pile driving from theoretical research and experimental research, and pointed out the problems existed in compaction effect. Finally, several suggestions on research methods and treatment measures to reduce the compaction effect are proposed.
