以节理岩体等效刚度的概念为基础，讨论了离散元刚性块体模型中节理刚度的选取问题。采用面-面接触模型模拟了纵波在一维岩体中的传播，给出了纵波波形；研究了阻尼比、软弱夹层以及节理间是否可拉对波传播规律的影响。 |

Based on the concept of equivalent stiffness of rock masses, the estimation of joint stiffness in distinct element model of stiff blocks is discussed. The propagation of P-wave in one-dimensional rock masses is analyzed according to plane to plane contact model. The P-wave shape is presented. The effects of damping, soft interlayer and tension property on the propagation characteristics are studied. |
