光面爆破技术在玉龙滩引水隧洞施工中的应用

The application of smooth blasting technique in the construction of seepage tunnel of Yulong beach

结合工程概况,对该引水隧道开挖方案的确定进行了分析,并从爆破器材及装药结构、掏槽形式、光爆主要参数、装药量、炮眼数量等方面介绍了爆破方案的选择,最后对该类引水隧道施工中应注意的问题进行了总结,以供类似工程参考。

Combined with the project general situation, it analyses the conformation of excavation program of seepage runnel, and introduces the selection of blasting program from the aspects of blasting equipment, loading structure, the forms of grooving, the main parameter of smooth blasting, charge, the numbers of shot hole, in the end it sums up the problems should be paid attention to in the construction of seepage tunnel, and this will give a reference to the similar projects.
