摘要
那兰水电站面板堆石坝为我国第一座将趾板置于河床覆盖层上的百米级高坝,坝体筑坝材料大部分采用砂砾料。设计中针对覆盖层及筑坝砂砾料的工程性质进行了深入研究,对趾板与地基的连接形式进行了多方案比较论证,解决了覆盖层上建面板坝的关键技术,并经实践检验,效果良好。
Dam of Nalan Hydropower Station is the first concrete face gravelfill and rockfill dam which is to exceed 100m in height and on deep alluvium in China, of which dam body is built with the badness gradation crude gravel and sand. In designing, it has put up deep researches on engineering character of alluvium and gravelfill material, and has also compared and demonstrated many schemes about junction form between plinth with foundation, which has advanced the key to solve the sixty-four-dollar question about CFRD on deep alluvium. It proves that the effect is good, based on practical work.
