大理岩的波速各向异性测量

Measurement of Wave Velocity Anisotropy

利用 GC- 1 0 0型工程多波参数分析仪 ,对山东莱州大理岩进行了波速各向异性的实验室观测。实验采用两组岩样 ,一组为带有先天的优势定向排列裂缝的岩样 ,另一组为带有优势层理走向的完整岩石。在未加载的状态下 ,发现两组岩样都有明显的波速方位各向异性。对于带有先天的优势定向排列裂缝的岩样 。

Using the GC 100 engineering multiple wave parameter analytical instrument,we measure velocity anisotropy of Laizhou marbles of Shandong in China.The result shows that there is obvious azimuthal anisotropy both for intact marbles(IM rock)with parallel laminations and for parallel cracked marbles(CM rock).Under the condition of unloading,shear wave splitting phenomenon also can be measured on CM rocks.
