| 摘 要： | 在室温常压下，通过对大量疏松砂岩的超声测定发现：（１）其纵，横波速度较低；（２）纵波速度ｖｐ在饱和水时比在饱和空气时有较大的增加；（３）横波速度ｖｓ在饱和水时比在饱和空气时略有降低；（４）纵，横波速度比ｖｐ／ｖｓ在饱和水时比在饱和空气时有较大的增加；（５），纵，横波速度与孔隙度呈线性关系。

| Abstract: | The ultrasonic test of multitudinous loose sandstone in ordinary atmospheric temperature and pressure leads to the conclusions: that both compressional wave and shear wave have quite low velocity. that compressional wave goes faster in water-saturated case than in air-satu-rated case. that shear wave velocity (vs) shows little slower in water-saturated condi-tion than in air-saturated condition. that the ratio of compressiona1 wave velocity to shear wave velocity (vp/vs)is higher in water-saturated condition than in air-saturated condition. that compressional and shear wave velocities are linear with porosity. |
