Numerical modeling of wave propagations in jointed rock masses

摘要：

In this paper, wave propagations in jointed rock bars are investigated by the discontinuous deformation analysis (DDA) method. A way for the selection of the numerical control parameters in the DDA modeling is presented. Through the DDA modeling examples, the attenuation of stress waves propagating in a jointed rock mass characterized by both decreasing the amplitude and filtering the high frequency components are well manifested. Besides the joint stiffness and loading frequency, the joint strength and the incident angle may also influence in the propagations of the stress waves remarkably.
