摘要
根据爆轰动力学和弹性波理论,分析了推算出水耦合装药爆破炮孔周围岩石中粉碎区和裂隙区半径,并用工程计算实例和ANSYS/LS-DANA数值模拟方法分析了装药不耦合系数对岩石破坏范围的影响。提出了炮孔水耦合炸药爆破在岩石中形成粉碎区时不耦合系数的计算方法,为光面爆破、预裂爆破装药结构参数的确定提供理论依据。
According to the dynamics of detonation and theory of elastic wave, the radius of the dispersed areas and the cracked areas enclosing the holes of Water - coupled hlasfing are analyzed and derived. The ANSYS/LS-DANA is used to caleulatean example of engineering and analyze the influence of coefficient of decoupling charge to the sphere of destroyed rock. A calculating method of coefficient of decoupling charge is presented when the dispersed areas in rocks is formed due to water-coupled charge blasting, providing a basic theory to define charge parameter of smooth blasting and presplitting blasting.
