公路隧道开挖常用爆破施工,首先必须进行爆破方案设计和爆破网络计算,其中最重要的基础工作就是计算和确定网络参数,进行炮孔布置和炮孔间距计算,最大允许装药量计算,单位用药量或单孔装药量计算,装药量分配等工作。本文重点的介绍了进行和完成这些基础工作的方法和计算公式。对广大从事爆破施工的工程技术人员,具有一定的指导价值。
Commonly used blasting construction of highway tunnel excavation, we must first blasting program design and blasting network calculation, of which the most important basic work is to calculate and determine the network parameters, the hole arrangement and spacing calculation, the maximum allowable charge calculation, unit Dosage or single-hole charge calculation, charge distribution and other work. This article focuses on the methods and formulas for conducting and completing these basic tasks. Explosive construction of the vast majority of engineering and technical personnel, has some guiding value.
