摘　　要：某水库枢纽选择夹岩—木连溪2.80 km范围的峡谷河段为建坝河段,需对其坝线和坝型进行比选分析研究,为设计此工程确定最优坝线及坝型。考虑枢纽布置、地形地质等综合因素,选择上、下两条坝线进行比较。上坝线位于卜口河罗家处;下坝线位于卜口河木连溪铜大高速(铜仁至大龙)木连溪大桥上游约310 m处,两条坝线相距260 m。经上、下坝线综合技术经济比较,下坝线混凝土面板堆石坝方案优于上坝线混凝土重力坝方案。在选定的下坝线位置拟定面板堆石坝和碾压混凝土重力坝两种坝型进行技术经济比较;根据勘探成果,结合筑坝材料、工程施工及运行期安全风险分析等,进一步做坝型选择分析研究。综合技术经济比较,面板坝方案优于重力坝方案。因此,此水库枢纽坝线及坝型经比选分析研究确定下坝线混凝土面板堆石坝方案。The gorge reach within 2.80 km from Jiayan to Mulianxi is selected as the dam building reach for a reservoir hydroproject.The dam line and dam type need to be compared, analyzed and studie Taking into account the topographic and geological conditions,layout conditions of the hydroproject, construction conditions and other factors, the upper and lower dam lines are selected for comparison. The upper dam line is located at Luojia of Bukou River. The lower dam line is located about 310m upstream of Mulianxi Bridge on Bukou River Mulianxi Tongda Expressway(Tongren to Dalong) The two dam lines are 260m apart. Through the comprehensive technical and economic comparison between the upper dam line and the lower dam line, the concrete face rockfill dam scheme on the lower dam line is superior to the concrete gravity dam scheme on the upper dam line. Two types of concrete faced rockfill dam and roller compacted concrete gravity damat the selected lower dam line are proposed for technical and economic comparison According to the exploration results, combined with dam building materials, project construction and safety risk analysis during operation, further analysis and research on dam type selection will be conducted. The comprehensive technical and economic comparison shows that the concrete faced rockfill dam scheme is superior to the gravity dam scheme. Therefore, the concrete face rockfill dam scheme for the lower dam line is determined through comparison, analysis and research on the dam line and dam type of the reservoir.
