Project design of the Guanjingkou Multi-purpose Project

观景口水利枢纽是重庆市重点水源工程之一,为Ⅱ等大(2)型工程。水库大坝、泄水建筑物及输水建筑物、永久支洞、控制建筑物及提水泵站等主要建筑物级别为2级。在工程建设中,根据现场实际情况,对导流洞线路布置、混凝土面板堆石坝趾板宽度、坝顶宽度进行优化设计,泄洪洞进口体形也进行了优化和调整,取得了较好的效果。

The Guanjingkou Multi-purpose Project is one of the key water sources of Chongqing City.The project is classified as grade II of large(2)type.Main structures such as reservoir dam,discharge structure and water conveyance structures,permanent adits,control structures and lift pump stations are grade two.Based on actual conditions during the engineering construction,the route of diversion tunnel is arranged.The design is also optimized for toe slab width and dam crest width of the concrete face rockfill dam,and the shape of inlet of the flood discharge tunnel,which shows a satisfactory result.
