| 摘 要： | 本文介绍了砂岩样品在干燥和饱和状态下,沿平行层理和垂直层理两个不同方向进行单轴加载时的抗压强度、变形特点和垂直于应力方向的P波走时的变化。结果表明,水对砂岩强度、P波速度的影响较大;具有原生层理构造的岩石样品的强度、变形和P波速度显示一定的方向性。所得结果对水库地震、工程地震、矿山开采及地震预报有一定的参考价值。

| Abstract: | This paper introduces how the sample of sandstone makes various changes of its strength, deformation and the travel time of P wave vertical to stress direction, under dry and saturation conditions and along with horizontal stratification and vertical stratification when the single axis oading is conducted.The results show that water makes an influence on the strength and the velocity of P wave of sandstone, and the sandstone sample of primary stratification has a definite direction of its strength, deformation and the velocity of P wave. The result is of the importance of reference to reservior earthquakes, seismic engineering and mines. |
