摘要
筠连县后沟水库坝址河段在平面上呈S形,河谷呈V形,河谷狭窄,河水陡涨陡落,无原河床分期导流和开凿明渠导流的条件,故考虑坝址右岸山体布置施工导流隧洞和坝下涵管导流方案。从施工工期,工程造价和施工强度等方面比较了这两种方案,最后采用布置施工导流隧洞的施工方案进行施工。
The river at the dam of Hougou reservoir in Junlian County is S-shape in plan and V-shape in valley.The river valley is narrow,the river surged and the steep fall in,so the river has no condition to diversion on the river bed and digging channel for diversion.During the dam construction,two schemes of construction diversion tunnel in the mountain at the dam and culvert pipe diversion are put forward.This paper compares the two schemes from construction period,construction cost and construction intensity etc.,and the construction diversion tunnel method is adopted.
