摘　　要：与常规渠化工程相比,在已建渠化梯级间增建航运梯级的坝址选择时,存在梯级间最低通航水位衔接和对已建电站发电影响分析等技术难题,研究案例较少。以嘉陵江水东坝航运枢纽工程坝址选择为例,采用对库尾河段水深、河势、地形地质、淹没损失等条件进行利弊分析的方法,提出坝址初选、枢纽建筑物布置和确定枢纽正常蓄水位的思路,从水位衔接、库区景观、对上下游已建电站发电影响、施工导流及工程投资等方面进行坝址综合比选。推荐复兴场坝址为水东坝航运枢纽建设坝址。Compared with the common canalization project,there are some technical problems of dam site selection,such as the connection of the lowest navigable water level between the hydro-junction and the analysis of the impact on the power generation of the built hydro-power station,when the dam site is added to the existing channelization cascades.The research cases are few.Taking the dam site selection of Shuidongba navigation hydro-junction project in the Jialing River as an example,we analyze advantages and disadvantages of conditions of water depth,river regime,topography and geology,and submergence loss of the section of the reservoir tail,put forward ideas of preliminary selection of dam site,layout of key buildings and determination of normal water level of key project,and carry out the comprehensive dam site selection from the aspects of water level connection,reservoir landscape,influence on power generation of built power stations,construction diversion and project investment,etc.The conclusion is that the dam site of Fuxingchang is recommended as the dam site of Shuidongba navigation hydro-junction.
