阳付沟水库坝址选择及枢纽建筑物设计

Dam Site Selection and Key Building Design of Yangfugou Reservoir

重力坝是一种常见的大体积混凝土挡水建筑物,其设计内容需要考虑多方面因素,其中坝址选择、水库枢纽建筑物设计是最重要的设计内容之一。根据《混凝土重力坝设计规范》,以仁怀市阳付沟水库为例,根据坝址地形地质条件、受水区分布高程、水资源条件等对建坝河段及坝址进行分析论证,并对其枢纽建筑物布置进行了设计。结果表明:在米山河支流阳付沟长槽至风岩沟洞河段建坝是最合适的选择。水库枢纽建筑物由堆石混凝土重力坝、开敞式溢流表孔及取水兼放空建筑物组成。

Gravity dam is a common mass concrete water retaining structure.Its design content needs to consider many factors,among which dam site selection and reservoir hydroproject building design are two of the most important design contents.According to Code for Design of Concrete Gravity Dams(SL319-2018),taking Yangfugou Reservoir in Renhuai City as an example,the damming reach and dam site are analyzed and demonstrated according to the topographical and geological conditions of the dam site,the distribution elevation of the water receiving area and water resource conditions.The layout of its hydroproject buildings is designed.The results show that it is the most suitable choice to build a dam in the reach from Yangfugou Changcao to Fengyangou Cave,a tributary of Mishan River.The hydroproject buildings of the reservoir are composed of rockfill concrete gravity dam,open overflow surface hole,water intake and venting structures.
