摘要
根据金平水电站坝址的水文气象和地形地质条件等基本资料,对砾石土心墙堆石坝和沥青混凝土心墙堆石坝进行技术经济比较。沥青混凝土心墙堆石坝防渗土料工程量小,施工环节少,占用土地少,环境影响小,施工技术成熟,工程投资省745万元,故采用了沥青混凝土心墙堆石坝方案,金平水电站已投产发电,运行良好。
Considering the hydrological-meteorological and topographical-geological conditions of Jinping hydropower station, two dam types, including the gravel soil core wall roekfill dam and the asphalt concrete core wall rockfill dam, are compared from the technical and economic aspects. It shows that the scheme of asphalt concrete core wall rockfill dam is of less construction quantity, few construction processes, less land occupation, small environment impact, mature construetion technology and less investment. Thus, the asphalt concrete core wall rockfill dam is finally selected for Jinping hydropower station. Practice shows that the operation of the station is satisfactory.
