摘要
为了描述露天矿单孔台阶爆破中预留岩体在爆炸冲击载荷下的损伤演化特征,建立了一个各向异性的损伤模型。模拟结果表明,该损伤模型能够模拟岩石材料在冲击载荷下的损伤特征,可以为岩土工程中经历过冲击扰动作用的岩体的稳定性分析提供理论依据。
An anisotropic damage model was established to describe the damage evolution characteristics of rock remain under single hole blast at open pit. The model is in good agreement with the experimental results. It provides a theoretical foundation for the stability analysis of rocks disturbed by impact load in geotechnical engineering application.
