摘要
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 。
To counter different kind of surrounding rock of Caoyuling tunnel engineering, different excavation programs of smooth blasting and the optimum blasting parameters are determined, therefore, the engineering quality is assured. Through practice, smooth-blasting is proved to be a effective method to tunnel-excavating, especially in complex geologic structure regions.
