云南黑龙水电站坝型选择初探

碾压混凝土坝具有温控措施简单、施工快、水泥用量少、投资省等优点。碾压混凝土技术在国内外大坝建筑中得到了广泛应用和发展。在预可行性研究阶段，从黑龙水电站坝址地形地质、枢纽布置、筑坝材料、施工、运行、投资及工期等方面，对碾压混凝土重力坝及混凝土面板堆石坝两种坝型进行分析比较后，初拟碾压混凝土重力坝为代表性坝型。

Selection of Dam Type of Heilong Hydropower Station

Roller compacted concrete dam have many advantages such as simple temperature control measure, easy con- struction, less cement usage, less investment etc., and it was widely used throughout the world. At the pre-feasibility study of Heilong hydropower station, roller compacted concrete gravity dam and rockfill dam with concrete facing were compared from topographic and geologic condition, project layout, dam material, construction condition, station opera- tion, project investment and construction period, roller compacted concrete gra,city dam was recommend finally.
