摘要
首先运用断裂力学的理论建立了岩石在单轴压缩条件下，轴向弹性波速与单轴压力的理论关系；然后运用信息理论方法建立了岩石细观力学参数的波动反演模型。理论模型的试算结果表明，本文建立的波动反演模型对岩石细观力学参数识别具有较高的精度。
A relationship between compressional wave velocily and stress under compressional loading is derived for rock block based on fracture mechanics theory,and an inversional model of micromechanics parameters estabilished according to information theory.The theoretical and numerical results show that the model is precise in inversion of micromchanics parameters of rock,and can be used to understand the rock micromechanism during deformation.
