本文分析了水、淤泥和岩土中爆炸的共性、特性以及不同尺度下的实验结果，讨论了岩土、淤泥中爆炸的运动规律，给出了描述气体膨胀及鼓包运动的特征时间。指出岩土中爆炸的鼓包运动主要是高压气体膨胀和介质惯性运动的结果。总结了鼓包顶点的运动速度和炸药能量间的关系。从中可以发现岩土的强度对鼓包运动的影响不大；或者说，岩土中爆炸的能量利用率与淤泥中爆炸的差别不大。
In this paper, we analyze the commonness and characteristics of explosions in water, mud and rock and the experimental results at different scales. The motion of explosions in soil and mud is discussed, and the characterization time of gas expansion and drum motion is given. It is pointed out that the explosion of drum in geomaterials is mainly the result of high pressure gas expansion and medium inertial movement. Summarizes the relationship between the velocity of the apex of drum and the explosive energy. It can be found that the strength of rock and soil has little effect on drum movement; or, the energy utilization rate of blasting in rock and soil is not different from the explosion in silt.
