摘　　要：　根据广西右江百色水利枢纽地下厂房复杂地质条件,提出了垂直孔光爆、水平孔光爆和垂直孔预裂等开挖方案,得出垂直孔光爆的效果最佳,水平孔光爆一次成形次之,垂直孔预裂方案最差的重要结论,对同类工程条件的爆破岩锚梁岩台开挖有重要的参考价值。In accordance with the complex geological condition of underground workshop of Guangxi Baise Water Conservancy Control Project, three excavation programs such as vertical hole smooth blasting, horizontal hole smooth blasting and vertical hole presplitting are put forward. The important conclusions are drawn that vertical hole smooth blasting is the most effective, the horizontal hole smooth blasting is the second, and the vertical hole presplitting is the most ineffective.
