摘要
以合武铁路大断面隧道工程为例,结合工程概况,简单介绍了全断面的开挖方法,阐述了钻爆设计原则,钻爆参数的选择及其掏槽方式,并对爆破效果进行了检查,对爆破设计进行了优化,以确保光面爆破的效果。
Taking tunnel works with large section in Hefei-Wuhan railway as example and combining general engineering situations full face excavation method is briefly introduced as well as drill-and-blast method.According to drill-and-blast method parameter selection,cutting method and design principle are elaborated.Optimum design is also made in order to ensure the effects of smooth blasting.
