摘　　要：DG水电站坝址区河谷狭窄,上下游分布有崩坡积体和泥石流沟,枢纽布置受地形地质条件限制较大。设计通过坝轴线、枢纽布置格局、筑坝材料等各方面比选,最终确定了碾压混凝土重力坝、左岸溢流坝段、右岸坝后式厂房的枢纽方案。该方案充分利用了坝址现有地形地质条件,总体布置合理、紧凑、开挖量适中、边坡支护工程量省,主要建筑物设计合理。The overall layout of DG Hydropower Station Project is greatly restricted by the topographical and geological conditions as the river valley is relatively narrow and colluvial deposits and debris flow gullies are found in the project site. After a comparison of several layout schemes considering the dam axis, overall layout and construction materials, a roller compacted concrete gravity dam scheme is selected, in which the overflow dam spillways are built on the left bank monoliths and the behind-dam powerhouses are built behind the right bank monoliths. This layout scheme fully utilizes the favorable topographical and geological conditions of the dam site. The overall layout is compact and reasonable with moderate excavation, less slope support work, and rational design of main structures.
