| 摘 要： | 利用Mises强度准则，并考虑岩石三向受力及其强度的应变率效应，导出柱状药包爆炸在岩石中引起的压碎圈与裂隙半径的计算式，进而对周边控制爆破的单孔装药量进行探讨。对于常见的岩石种类，计算式能取得与爆破实际相符的结果。

| Abstract: | The formulae are deduced for calculation of the radii of the smashed and cracked areas in rock by a long charge explosion, with the Mises' strength criterion. Meanwhile, the three-directional load and strain-rate effects of rock are taken into consideration. Then, the explosive charge for the controlled perimeter blasting is discussed. For the familiar rocks, the values from the formulae accord with blasting practice. |
