【Abstract】 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.更多还原
