金沙江白鹤滩水电站交通隧道衬砌质量精细化管理

Fine management of lining quality in Jinsha River Baihetan Hydropower Station transportation tunnel

金沙江白鹤滩水电站是仅次于长江三峡水电站的中国第二大水电站,在筹建期四通一平工程非常重要,尤其是场内交通道路的形成,是制约全面开展工程建设的关键。部分永久交通干线为施工期与运行期所共用,建设初始就必须严格控制施工质量,实现优良的工程质量目标。本文以白鹤滩水电站左岸公路上村梁子隧道工程为实例,全面总结了隧道衬砌施工质量的精细化管理方法,对同类工程有较强的借鉴意义。

Jinsha River Baihetan Hydropower Station is the second largest hydropower station in China following to Yangtze River Three Gorges Hydropower Station. The four-connection and one leveling project under construction is very important,especially formation of traffic roads in the construction site is critical for limiting comprehensive construction of project. A part of permanent traffic trunks are shared in both construction period and operation period. Construction quality should be strictly controlled at the beginning,thereby realizing high-quality project quality objective. In the paper,Cunliangzi Tunnel Project on the left bank highway of Baihetan Hydropower Station is adopted as an example for comprehensively summarizing the fine management method of tunnel lining construction quality with stronger reference significance for similar projects.
