| 摘 要： | 通过算例验证了利用UDEC研究应力波在节理位置传播时的透射率的可靠性；基于所定义的中线截距平均值与节理起伏均方根，建立了10种含不同粗糙程度的节理模型。研究表明，当节理的中线截距平均值相同时，应力波通过粗糙节理的透射率随节理起伏均方根的增大而降低；当节理起伏均方根相同时，应力波通过粗糙节理的透射率随节理中线截距平均值的增大而增大。

| Abstract: | The reliability of calculation of the UDEC has been proved by an example which about the transmitting of stress wave through a joint.Ten kinds of models with different level of roughness joints has been established based on average centerline intercept and root mean square value of relief amplitude of joint.The numerical results show that transmittivity of stress wave decreases with root mean square value of relief amplitude increasing while keeping average centerline intercept same, and also transmittivity will increases with average centerline intercept increasing while the root mean square value of relief amplitude keeping same. |
