摘　　要：基桩动测系统中由于传感器在桩顶的耦合而改变了原系统的动态模型 ,从而使系统的动态响应也发生变化。文章对基桩动测中常见的几种耦合剂对系统频响特性影响情况作了理论分析和实验验证 。In dynamic testing system of piles,the dynamic model and frequency response of the system were changed due to the coupling effect of coupler between transducer and pile. In this paper, the study of the response function of testing system affected by several couplers was carried out by means of theoretical analysis and experiment. The valid frequency scopes of some couplers were given.
