Layered filling structure of rockfill material transition area of face rock-fill dam and construction method
The invention provides a layered filling structure of a rockfill material transition area of a face rock-fill dam and a construction method. The transition area structural form of primary rockfill area and secondary rockfill area filler layered alternate filling is arranged between an upstream primary rockfill area and a downstream secondary rockfill area, interbedding filling of soft and hard rockfill materials is adopted, transition of upstream and downstream rockfill materials is achieved, the problem of the large deformation modulus difference between the upstream high-quality primary rockfill area and the downstream poor-quality secondary rockfill area is solved, and the machining cost problem caused by independent design of transition area filler can be avoided; and meanwhile, the transition area filler source range is widened, technical guarantees are provided for application of a large quantity of completely and intensely weathered excavated materials to filling of the downstream secondary rockfill area in engineering, the rockfill material zoning structure is simplified, construction efficiency is improved, and the engineering investment is also saved.
本发明提供了一种面板坝堆石料过渡区的分层填筑结构与施工方法，通过在上游主堆石区和下游次堆石区之间设置主堆石区与次堆石区填筑料分层交替填筑的过渡区结构型式，采用软硬堆石料的互层填筑，实现上、下游堆石料的过渡，解决了上游质量好的主堆石区与下游质量差的次堆石区之间较大的变形模量差异问题，可避免单独设计过渡区填筑料所导致的加工成本问题，同时也扩大了过渡区填筑料料源范围，为工程中大量的全、强风化开挖料在下游次堆石区填筑应用提供了技术保障，并且简化了堆石料分区结构，提高了施工效率，也节省了工程投资。
