摘要
渝怀线正阳隧道地质复杂 ,溶洞、溶槽、节理裂隙发育 ,涌水量大 ,设计铺设防水板 ,光爆效果的好坏将直接影响防水板的挂设与衬砌混凝土的质量。本文对该隧道的光面爆破施工技术作了简单介绍 ,总结了几点体会。
The geologic condition of Zhengyang Tunnel on Chengdu-Huaihua Railway Line is comlpex,whth gaps developing of kast cave,fluid bowl and joint,and much water gushing.Therefore water-proof plates should be laid.The result of smoothwall blasting directly influences on the quality of liner concrete.A brief introduction to the smoothwall blasting technique for Zhengyang Tunnel is given and some experience summed up in this paper.
