摘　　要：本文介绍了在某岩质边坡水库中修建输水隧洞取水口的优化设计方案。该设计方案通过水下沉管与浇筑水下混凝土的方式,施工永久性人工岩塞体与取水口;在该永久性人工岩塞体的保护下,输水隧洞安全开挖至取水口位置,实现取水头部的贯通。设计优化方案与常规围堰法或岩塞爆破法相比,具有安全性高、施工工期短、取水口水流条件好、工程难度低等优点。本文可为类似的工程提供借鉴与参考。This paper introduces an optimal design scheme for the water intake of a water conveyance tunnel in a rock slope reservoir.The design scheme constructs permanent artificial rock plug and water intake by means of sinking pipe and underwater concrete.Under the protection of the permanent artificial rock plug,the reservoir tunnel can be safely excavated to the water intake position,to achieve penetration with the water intake head.Compared with conventional cofferdam method or rock plug blasting method,this method has the advantages of high safety,short construction period,good flow condition and low difficulty.This paper provides reference for similar projects.
