软土地基中单桩施工引起的超孔隙水压力

Excess pore water pressure caused by an installing pile in soft foundation

通过对桩基施工过程中实测资料的分析,探讨了沉桩时单桩周围土中产生的超孔隙水压力的大小、分布及影响范围,并与理论解进行了对比。还对桩-土界面处的超孔隙水压力进行了讨论。

By analyzing of the results measured during construction of pile foundation, the magnitude, distribution and range of the excess pore water pressure caused by an installing pile in soil around the pile are discussed; and are compared with theoretical estimates. The excess pore water pressure at the interface of the pile and soil is discussed too.
