摘　　要：通过监测预应力管桩动力冲桩过程中路基内孔隙水压力的变化,分析了冲桩振动对砂质路基液化的影响情况,从而为类似场地及工作条件下选择适当的压桩工法提供依据。By monitoring the change of pore water pressure within the foundation during the dynamic impact of the prestressed pipe piles,the paper analyzed the effect of vibration result in impacting pile on liquefaction of sandy highway foundation,which is similar to the site and working conditions,choose the appropriate piling construction method to provide the basis.

关 键 词：预应力管桩 冲桩 孔隙水压力 液化
