摘要
Abstract
Compared with ordinary rock mass,the structure of the weir dam is very loose,which is not conducive to the propagation of elastic waves.In this paper,a high-power source and a high-sensitivity geophone are used to carry out elastic CT tests to evaluate its application in the evaluation of the compactness of the weir dam feasibility.The results of forward modeling show that the elastic CT method can reflect the internal medium structure and wave velocity of the loose accumulation body;the inversion wave velocity of the elastic CT method in the borehole carried out on the on-site dam accumulation body is com-pared with the drill core.With good correspondence,the CT velocity profile can comprehensively reflect the compactness of rock and soil between boreholes.The results of this paper show that the longitudinal wave velocity obtained by the elastic CT method can effectively evaluate the underground compactness of the weir dam.关键词
