摘要(Abstract)：

简述了戴峪岭2号隧道的工程情况,针对其围岩地质条件差,采用光面爆破进行隧道开挖。优化设计了各种炮孔爆破参数,实现了开挖轮廓整齐、维持岩体稳定、安全快速施工的目的;并对此工程的施工要点和效果进行了总结与分析。
The engineering situation of Daiyu ridge was introduced.According to poor surrounding rock,smooth blasting technology was adopted to excavate the tunnel.Blasting parameters of various boreholes were optimized and designed.The purpose was realized that excavation contour was neat,rock-mass stability was maintained,and construction was safe and fast.Moreover,key points and effect of the construction were summarized and analyzed.
