青龙水电站引水隧洞工程地质条件及洞线优化

摘要

指出青龙水电站为长隧洞引水式电站,隧址区岩性主要为板岩和灰岩,根据施工支洞揭示的地质情况,修正完善了隧址区的地质资料,进而对引水隧洞洞线进行了合理优化,取得了较好的效果。%The paper points out that Qinglong hydropower station belongs to long tunnel diversion-style station and the lithologic is stabstone and limestone.According to the branch tunnel construction geology conditions,it modifies the geological materials of the tunnel site,further rationally optimizes diversion tunnel route,and finally achieves better achievements.
