| Abstract: | The mechanical properties of the Mogao grottoes are studied by the sonic wave test in the present paper. It is indicated that the longitudinal wave speed, shear wave speed, as well as the dynamic Youngs modulus of the Mogao grottoes increase with the increasing depth of grottoes. The mechanical properties of the grotto top are worse than those of grottoes bottom. In addition, the sonic wave velocity parallel to the rock stratum is higher than that perpendicular to the rock strata. |
