| 英文摘要 | The 3D-NDDACP method (nodal-based 3D discontinuous deformation analysis method with contact potential) shows its capability to simulate discontinuous deformation of rock block systems. Due to the adoption of contact potential for contact treatment and Newmark method for time integration, 3D-NDDACP method inherits attractive advantages from both FEM-DEM and discontinuous deformation analysis (DDA) method. Furthermore, tetrahedral meshes are adopted to discretize rock blocks to model their deformation. In this study, 3D-NDDACP method is enriched to simulate wave propagation in rock masses. The new enrichments to the 3D-NDDACP method include: 1) a viscous nonreflecting boundary is firstly adopted to absorb wave energy to minimize the negative effects from artificial boundaries; 2) on the basis of viscous nonreflecting boundary, a viscoelastic boundary is adopted to simulate the elastic recovery property of an infinite problem domain; and 3) to accurately input incident wave, the force input method is adopted. To validate the enriched 3D-NDDACP method, a series of typical numerical tests associated with P/S-wave propagation through jointed/homogeneous rock masses are conducted. Results from these numerical tests show that the enriched 3D-NDDACP method is able to correctly and reliably model the processes of P/S-wave propagation across homogeneous and jointed rock masses. |
