摘　　要：从反射波法检测的基本原理入手,通过工程实例论述了场地条件,如土质、施工工艺等对低应变时域反射波曲线的影响,总结了土阻力及不同的成桩工艺对反射波形的影响规律,有利于指导工程实践。Starting from the basic priaciples of the backscatler wave monitoring and an engineering example, the field conditions such as soil characteristics construction technology etc. which effect on the low strain time domain backscatler wave. The rules that the resistance and different pile installation effects the shape of backscatler wave is summarized.
