| description | Finite element models of specimens which imitated rock slopes were made to validate applying the hammering method on the stability estimation of rock blocks. At first, transient response analysis was done. We confirmed validity of analysis models because the sound pressure spectrums were most of the same with the velocity spectrums. Next, modal analysis were done, we studied about the vibrating situation of the specimens in the experiment. As the result, it was shown that we could recognize vibrating situation that concerned the stability of the rock blocks by hammering method. And it was shown that we could apply hammering method on the quantitative stability estimation of rock blocks. In addition, transient response analysis was done for recognizing the influence on the difference of the size of the rock blocks and the modulus of direct elasticity. As the result, the difference of them influenced on the result of the hammering method, the result showed the difference of the stability of the rock blocks. In the end, we measured the sound pressure spectrums at the real rock slopes. We confirmed that it is possible to comprehend the rock stability by hammering method. |
