Reservoir connecting structure of concrete faced rockfill dam and deep backfill reservoir bottom and construction method
The invention discloses a reservoir connecting structure of a concrete faced rockfill dam and a deep backfill reservoir bottom and a construction method.The connecting structure comprises a reservoir bottom backfill rock ballast area, a concrete panel on the upstream of the concrete faced rockfill dam and a toe board arranged at the lower end of the concrete panel, and the upper portion of the reservoir bottom backfill rock ballast area adopts a geomembrane anti-seepage layer for seepage prevention; a main rockfill area is arranged below the concrete panel; the toe board is horizontally connected with the geomembrane impermeable layer, and a supporting platform is arranged at the bottom of the toe board; the main rockfill area extends towards the side of the reservoir bottom rock ballast backfilling area, and the bottom of the supporting platform is located on the main rockfill area. According to the reservoir connecting structure of the concrete faced rockfill dam and the deep backfill reservoir bottom and the construction method, the supporting platform is arranged, and the upstream cushion layer area and the transition area of the dam body extend to the bottom of the toe board to serve as a part of the supporting platform, so that the toe board foundation is located on the dam rockfill body; and toe board deformation and stress influence caused by differential settlement of the deep backfill body in the later period are effectively reduced.
本发明公开了一种面板堆石坝与深厚回填库底的水库连接结构及施工方法，连接结构包括库底回填石渣区、面板堆石坝上游的混凝土面板和设置在混凝土面板下端的趾板，库底回填石渣区上部采用土工膜防渗层防渗，混凝土面板下方设有主堆石区；趾板与土工膜防渗层水平连接，趾板底部设有支撑平台；所述主堆石区向库底回填石渣区侧延伸，支撑平台底部位于主堆石区上。本发明的面板堆石坝与深厚回填库底的水库连接结构及施工方法，通过设置支撑平台，并将坝体上游垫层区和过渡区往趾板底部延伸作为支撑平台的一部分，使得趾板基础坐落于大坝堆石体上，有效减少了深厚回填体后期的不均匀沉降引起的趾板变形和应力影响。
