摘要(Abstract)：

针对较差岩性围岩条件下小断面隧道开挖的施工特点,探讨了相应条件下小断面水工隧道光面爆破技术,得到了合理的钻爆参数,改善了水工隧道成洞质量,减少了超欠挖,加快了爆破开挖速度,有关参数与技术措施可为同类工程提供参考与借鉴。
The smooth blasting technique was researched for the small section hydraulic tunnel according to poor lithology surrounding rock,and some reasonable parameters were obtained.Thus the quality of boreholes has been improved,over-under-excavation of the tunnel has been controlled effectively,and the progress of blasting excavation has been accelerated as well,which could provide reference for similar projects.
