Abstract
Numerical study on wave transmission across jointed rock masses is performed with a DEM-based code UDEC. As the first step, the numerical results of wave transmission across rock joints are compared with analytical solutions and in-situ data. Good agreement among them validates the capability of UDEC in modeling wave propagation. Extensive parametric studies on wave transmission across jointed rock masses are subsequently conducted. It is found that joint mechanical and spatial parameters including joint normal and shear stiffnesses, nondimensional joint spacing, joint spacing ratio, joint intersecting angle, incident angle and number of joint sets together determine the wave transmission. However, compared with other parameters, joint normal stiffness, nondimensional joint spacing and joint intersecting angle have more significant effects. The physical reasons lying behind those phenomena are explained in detail.
