| 摘 要： | 岩石所受的三向应力状态对其弹性波传播性质有一定的影响，此认识为所做的以泥质砂岩、泥岩和硅质胶结的坚硬砂岩为试样的实验所证实。实验结果表明，泥质砂岩和泥岩的ｖＰ／ｖＳ值几乎保持不变，硬质砂岩的ｖＰ／ｖＳ曲线却在应力达破坏荷载的９０％左右出现下凹现象。经热处理后的硬质砂岩这一下凹现象则更突出

| Abstract: | The influenes of triaxial stress states on the elastic wave velocities of clayey sandstone,and claystone and hard siliceous sandstone have been determined by experiments.Claystone and clayey sandstone show hardly any changes in the v P/v sratio.For siliceous sandstone there is a minimum in the ratio of the wave velocities at 90% of the failure stress.This minimum especially present in the siliceous sandstone previously treated with heat. |

| Keywords: | rock stress state elastic wave |
