摘　　要：针对在役结构下部基桩应力波测试方法,从去除近场、远场干扰信号的角度出发,深入探讨了现有的低应变测试方法中的单点采样法、双速度法、双速度平均法、数值计算消除法及属于应力波范畴的平行地震波法各自的优缺点,为基桩检测人员对测试方法的选择提供了参考。This paper focused on the stress wave test method to the pile foundation of the existing structure,from the point of view of removing of interference signal in near field and far field,deeply discussed the respective merits and demerits of single point sampling method,double velocity method,double velocity average method,numerical elimination method which were included in the category of low strain test method,and also the parallel seismic wave method which was included in the category of stress wave test method,and this provided the reference to the selection of test method for pile foundation inspector.
