前言爆炸物在土岩介质中激发引爆,爆炸波一瞬间就在土岩介质中传播.这种瞬时加荷引起土体或岩体变形、破坏和振动是爆破过程的普遍特征.这一过程受许多因素的影响:例如介质的物理力学特性,爆源的埋没深度,爆炸物的性质,爆炸体的大小和结构,起爆方式,爆破作用指数等等.由于对这一过程的物理实质还未研究透彻,对它的解释也各式各样,以至到目前为止尚没有一个公认的理论.
Foreword Explosives ignite and detonate in earth-rock media. The blast wave propagates in the earth-rock medium instantaneously. This instantaneous loading causes deformation, damage, and vibration of the soil or rock mass. This is a common feature of the blasting process. The influence of many factors: for example, the physical and mechanical properties of the medium, the depth of the buried source, the nature of the explosive, the size and structure of the explosive, the mode of initiation, the index of the blasting action, etc. Since the physical nature of this process has not been studied Thoroughly, the interpretation of it is also varied, and so far there is no universally accepted theory.
