摘要
通过对烘干和饱水状态下的大理岩进行纵波波速测试 ,发现饱水后的大理岩波速将发生变化并表现出明显的分散性 ,波速的各向异性也被弱化 ,长期浸泡后 ,大理岩的波速还可能会降低。引入绕射系数 k,对 Wyllie公式加以完善 。
The effects of saturation in water on wave velocity for marbles are of dispersing feature. Water can weaken the anisotropy of the wave velocity. After a long term saturation, the wave velocity of marble will be reduced. These results are obtained by many longitudinal wave tests of marbles. By introducing the new concept--coefficient of detour k and applying it to the Wyllie′s formula, a satisfying analysis result is given.
