针对草峪岭隧洞工程中不同特性的围岩 ,选用了不同的光面爆破开挖程序 ,确定了最佳爆破参数 ,保证了工程质量 .实践证明 ,光面爆破是隧洞开挖 ,特别是地质构造比较复杂地区隧洞施工行之有效的方法
According to the different characteristics of surrounding rock in the Caoyuling tunnel project, different smooth blasting excavation procedures were chosen to determine the best blasting parameters and ensure the project quality.It has been proved that smooth blasting is the key point of tunnel excavation, especially geological Construction of more complex tunnel construction effective method
