基于损伤模型的圆形洞室矿震分析
|
摘要
采用应变损伤模型对圆形洞室矿震的发生进行了解析分析,得到了发生矿震的洞室临界塑性区深度和临界作用力,得出损伤内变量 k0,kc是决定圆形洞室矿震发生的重要参数。
Based on strain damage model, the occurrence of circular chamber mine earthquake is analyzed .The critical plastic depth and critical load of circular chamber mine earthquake are obtained. It is concluded that the damage internal variables k0 and kc are important parameters determining the occurrence of circular chamber mine earthquake.
