以物体高速撞击局部效应与冲击能量因子密切关系为启迪,首次提出深地下围岩“一高二扰动”等效平均振动能量原理及其表达式,根据深部岩体准共振和摆型波现象出现的量纲一能量条件,深入阐释该条件的物理基础并定义之为地冲击能量因子。论文推导了深部围岩岩爆、分区破裂时空构造与地冲击能量因子的关系;根据地冲击能量因子发生动力灾变的阈值,结合地下大规模爆炸地冲击运动的传播规律,界定了防护工程安全埋置深度。研究表明:地冲击能量因子为探明深部岩体力学复杂静动力学现象与工程响应关键机制开辟了新的研究途径。
Based on the close relationship between the local effect of high-velocity impact and the impact energy factor, the principle and expression of the equivalent mean vibrational energy of deep underground rock “high-secondary disturbance ” are proposed for the first time. According to the phenomena of quasi-resonance and pendulum wave The appearance of a dimensional energy conditions, in-depth interpretation of the physical basis of the condition and defined as the impact energy factor. According to the threshold of dynamic catastrophic impact of the impact energy factor, combined with the propagation rule of the impact of large-scale underground explosion, the paper defines the safe embedding of protective engineering depth. The results show that the ground impact energy factor has opened up a new approach for the exploration of the complex mechanics of deep rock mass and the key mechanism of engineering response.
