摘    要:在分析研究现有岩石爆破损伤模型和岩石损伤断裂理论的基础上,有杉计算有效弹性模量的Taylor方法建立了一个新的岩石爆破损伤模型,提出了岩石在爆炸应力波作用下的损伤断裂准则,以DYNA2D程序为基本框架,采用小损伤条件下的解耦方法,对大理岩在填塞和不填塞装药条件下的损伤历程进行了数值模拟。

关 键 词:岩石爆破  损伤模型  数值模拟

Abstract:Based on the existing damage model of rock blasting and the theory of rock damage and fracture, a new damage model for rock blasting is proposed by using the Taylor method of calculating effective elastic moduli The damage and fracture criterion during the explosive stress wave is presented Based on the structure of DYNA-2D, numerical simulation of the rock blasting process is realized by use of the decoupled method under small damage
Keywords:rock blasting  damage mechanism  numerical simulation
