摘要
本文用伪谱法模拟了弹性波在具有一个平直界面的介质——一部分是无裂缝岩石 ,另一部分是含有固定方向排列裂纹的这种岩石中的传播。主要就介质的各向异性界面及裂纹的排列方向对波的共同作用进行了模拟和分析。结果表明 ,裂纹的排列方向及界面的位置不同 。
The paper simulated the propagation of elastic wave in a medium with horizontal interface by pseudo spectral method (PSM).The medium consists of two parts: one part is rock without fracture,the other part is rock with fracture aligned along fixed direction.The paper mainly simulated and analyzed the common action of heterogeneous interface of medium and aligned direction of fracture on elastic wave.The results showed that the different positional relations between aligned direction of fracture and interface have different effects of interface on elastic wave.
