摘　　要：在预制桩施工过程中,通过在已建建构筑物的周边布置位移与孔压监测点,监测深层土体水平位移与孔压变化,可了解建筑物下的基桩内力与变形受挤土的影响,并对其安全性作出评价。In the construction of precast piles, the variations of the horizontal displacement and pore pressure of deep soil were monitored through the observation points arranged around the existing building so as to understand internal force and deformation of the pile foundation under the existing building affected by the squeezed soil and make a safety evaluation.

关 键 词：挤土 监测 安全 评价
