查询词典 wind wave

In the process of impact of abrasive jet on rock, resulting dynamic stress plays an important role in rock destruction. The stress wave resulted makes local rock tensile and shearing, then makes rock destructed. In the conditions of some hypotheses, the mechanical model that rock is applied by stress wave, i.e. jet wave basic equations, are set up by wave theory, and the formula of the maximum normal stress resulted by stress wave is deduced according to known boundary conditions.

The experimental results show that the estimated strength of cylindrical specimens and core specimens taken from plate-like specimens under the condition of saturated surface-dry were good and the difference between the estimated strength and the measured strength is within 10%. For the plate-like specimens used in this study, measured the surface P-wave and internal P-wave, and investigate the difference between surface P-wave and internal P-wave velocities. Firstly, the internal P-wave velocity was recovered to the saturated surface-dry condition.
