糯扎渡水电站坝料填筑施工工法及质量控制

Construction Methods and Quality Control of Dam Embankment Materials,Nuozhadu Hydropower Project

糯扎渡水电站高心墙堆石坝采用掺砾土心墙,坝料分区、料源种类多、施工工艺复杂,多项施工参数超过现有土石坝施工规范。文章阐述了糯扎渡水电站大坝坝料填筑施工工法及质量控制,满足了施工进度和质量要求。

The rockfill dam with high cutoff wall of Nuozhadu Hydropower Project applied the cutoff wall of soils with gravel mixed. Zones for material embankment and material types are various. The construction technology is complicated. A couple of construction parameters are beyond the requirements stipulated in the construction specification for earth-roekfill dam. Construction methods and quality control of dam embankment materials, Nuozhadu Hydropower Project, are described in this paper, which satisfy requirements on construction schedule and quality.
