| 摘 要： | 为了解决空腔膨胀理论在研究介质中侵彻与爆炸破碎区过程存在的问题及分析其产生的原因，从破碎区应力与变形状态的实际出发，运用动量与质量守恒关系，推导出介质破碎区运动学的关系式，在此关系式基础上，给出侵彻、贯穿比例换算关系和爆炸破碎区的几何相似关系等简单实用结果，应用于构造特性的材料中。

| Abstract: | The tendencies of fundamental problems of the fragmentation zone of the cavity were reviewed under the explosion and penetration in rock mass. The relation formula of velocity field of medium was deducted with conservation relation of momentum and mass according to stress and deformation state near the cavity in practice. The results available (such as proportional conversion relation of penetration and impenetration, geometrical similar relation of explosion) were obtained with proposed velocity relation, and were applied to material of constructional feature. |
