摘要
某水利枢纽发电洞洞身工程围岩类别以Ⅲ,Ⅳ为主,通过生产性试验确定洞室开挖爆破的施工参数及施工工艺,指导发电洞洞身工程的开挖。试验表明爆破没有对爆破区岩体产生破坏性影响,爆破残孔率较高,残留炮孔痕迹分布均匀,相邻两孔间的岩面平整,孔壁无明显的爆破裂隙,试验爆破确定的参数可为同类引水隧道或其他隧道工程提供参考和借鉴。
The surrounding rock of the power tunnel of a water conservancy project is mainly classified asⅢandⅣ.The construction parameters and technology of the excavation and blasting of the tunnel are determined through the productive test to guide the excavation of the power tunnel.The test shows that the blasting has no destructive effect on the rock mass in the blasting area,the rate of residual holes is high,the traces of residual holes are evenly distributed,the rock surface between two adjacent holes is flat,and there is no obvious blasting crack in the hole wall.The parameters determined by the test blasting can provide reference for the similar diversion tunnel or other tunnel projects.
