摘要
静压桩施工过程中会对周围环境造成不利影响。结合工程实例进行沉降、位移和超孔隙水压力监测,发现临近建筑物中部隆起位移比两端大;迎向压桩开展方向面土体的水平位移量大于背向面;静压桩机有可能造成周围建筑物向施工场地倾斜;超孔隙水压力随着离开桩的距离非线性衰减,其有效影响半径为15 m左右。
The construction process of a press-in pile may lead to adverse effects on surrouding civil works.The in-situ monitoring tests were carried out in a practical construction.It is found that the central uplift displacement of surrounding buildings is lager than both of ends.The horizontal displacement along the direction of pressing is lager than back surface.The surrouding buildings may slope to construction site by pile pressing-in machine.The excessive pore water pressure is dying out with the distance extending from the pressing-in pile,and the effective radius is about 15 meters.
