一、前言水利、铁道、冶金等工业部门,在基坑开挖、隧道掘进,矿山开采等作业中通常用圆柱状条形药包.此外,某些工程如洞库爆炸也可看成条形药包.显然,这类药包在岩体中爆炸时,应力波的传播和动应力的分布均不同于球形药包的爆炸而具有自己的特点.这些特点直接影响爆破破岩机理和对地下工程施加动荷载的特征,以及对它的动态稳定性的评价.因 I. INTRODUCTION Water conservancy, railways, metallurgy and other industrial sectors usually use columnar cartridges for pit excavation, tunnel excavation, and mining operations. In addition, some projects such as cave explosions can also be viewed as bars. Drug packs. Obviously, when such explosives explode in rock masses, the propagation of stress waves and the distribution of dynamic stress are different from those of spherical explosives and have their own characteristics. These characteristics have a direct impact on the mechanism of blasting and the underground The characteristics of the dynamic load imposed by the project and the evaluation of its dynamic stability.
