摘要
在信江下游鄱阳湖区,地形水系复杂,河流分汊较多,坝址选择的河段范围大,枢纽坝址的方案选择较复杂.以信江八字嘴航电枢纽工程为例,在确保各坝址枢纽满足通航要求且与上下游梯级衔接的基础上,采用对各坝址枢纽功能、河道及两岸地形、建筑物布置合理、减少库区淹没等条件进行分析利弊的方法,提出坝址选择的思路,从地形地质条件、枢纽布置、工程量、通航条件、航道衔接条件、施工条件、库区淹没、工程总投资等方面进行坝址综合比选,得出八字嘴航电枢纽工程的推荐坝址.通过方案论证梳理坝址选择和枢纽布置的思路,成功解决了河口湖区复杂水系地形条件下的坝址选择难题.
Abstract
The Poyang Lake area,at the downstream of the Xinjiang,is featured by complex terrains and water system with multiple river branches.The selection of dam site has a large range of river sections,and the selection of the scheme of the hub dam site is complicated.Taking the Bazizui navigation and hydropower hub project in the Xinjiang as an example,based on meeting the requirements for navigation and the connectivity of the cascade in the upstream and downstream areas,we use a methodology for analyzing the pros and cons of various dam sites considering the functionality of each dam site,reasonable arrangement of river channels and banks,building layout,and minimizing reservoir inundation,and propose the idea of dam site selection.Then we carry out comprehensive comparison and selection of dam site selection from topography,geology,hub layout,project quantity,navigation conditions,channel connectivity,construction conditions,reservoir inundation,and overall project investment,and obtain the recommended dam site for the Bazizui navigation and hydropower hub project.Through a demonstration of the scheme,we clarify the strategy for dam site selection and hub layout,and successfully solve the problem of dam site selection in the complex water system and topographical conditions of the river mouth lake area.
