摘    要:岩体是复杂的等级构造地质体,在高地应力作用下,因摩擦和粘结作用,内部封存能量,可看作具有内部能量源和能量汇的介质。基于岩体块系构造, 对岩体在扰动下的运动积分和等效动能进行分析,提出了在高地应力赋存环境中岩体受爆炸地震波扰动下的等效地冲击能量因子,并给出了大规模地下爆炸诱发远区局部不可逆范围的计算公式。与G.G.Kocharyan等基于块体运动分析给出的计算公式比较表明,本文中提出的计算理论物理过程清晰,更具有适用性。

关 键 词:大规模地下爆炸  岩体块系构造  等效平均动能  局部不可逆变形

Abstract:Being of a complex hierarchical structure with energy closed in it for its intrinsic friction and cohesion,the rock mass can be regarded as a medium with the properties of internal energy source and energy collection.The equivalent impact energy factor corresponding to the rock mass under high in situ stress subjected to the weak disturbance was presented,and the calculation method of the irreversible deformation region radius under the large-scale underground explosion was deduced.Compared with the method by Kocharyan G G,et al,the calculation method presented in this paper has a clearer physical principle and wider application.
Keywords:large-scale underground explosion  block hierarchy structure  equivalent average kinetic energy  local irreversible deformation
