The location of shear strain rate localization coincides in position with the location of volumetric strain rate, which is the actual failurezone of rock.
剪切应变率（或应变）局部化区域与体积应变率（或应变）的位置重合，局部化区域就是岩样最终的破坏位置。
2
The range of fracture failure zones under the influence of blasting stress wave was identified and the calculation formula of the failurezone was also proposed.
研究了爆炸应力波作用下裂隙岩体断裂破坏范围并提出了新的破坏范围计算公式；

The results show that: 1 the destruction develops first from the center line of both sidewalls of roadway, after the local failure, there gradually formed a pair of "wedge" failurezone.
