Earth and rockfill dam structure for pumped storage power station reservoir and construction method of earth and rockfill dam structure
The invention provides an earth and rockfill dam structure for a pumped storage power station reservoir and a construction method of the earth and rockfill dam structure, and relates to the technical field of water conservancy and hydropower engineering.The earth and rockfill dam structure comprises a dam body formed by earth and rockfill materials generated during reservoir basin excavation, an anti-seepage core wall is arranged in the center of the dam body, and an anti-seepage curtain extending to the depth of a dam foundation is arranged at the bottom of the anti-seepage core wall; the inner side of the anti-seepage core wall is provided with an inner side rockfill area, and a first transition area is arranged between the inner side rockfill area and the anti-seepage core wall; a second transition area, a cushion layer area and an anti-seepage panel are sequentially arranged on the inner side slope surface of the inner side rockfill area; an outer side rockfill area is arranged on the outer side of the anti-seepage core wall, and a third transition area is arranged between the outer side rockfill area and the anti-seepage core wall; the dry block stone revetment is arranged on the outer side slope surface of the outer side rock-fill area, the problems of environmental protection and economical efficiency caused by earth-rock absorption and large waste slag amount are solved, and the method is suitable for design and construction of upper and lower reservoirs of the pumped storage power station needing bidirectional water retaining, seepage prevention and flood prevention.
本发明提供了一种用于抽水蓄能电站水库的土石坝结构及其施工方法，涉及水利水电工程技术领域，包括由库盆开挖时产生的土石料构成的坝体，坝体的中心设有一道防渗心墙，防渗心墙的底部设有向坝基深处延伸的防渗帷幕，防渗心墙的内侧设置内侧堆石区，内侧堆石区与防渗心墙之间设置第一过渡区；内侧堆石区的内侧坡面上依次设置第二过渡区、垫层区和防渗面板；防渗心墙的外侧设置外侧堆石区，外侧堆石区与防渗心墙之间设置第三过渡区；外侧堆石区的外侧坡面上设置干砌块石护坡，解决了土石方消纳及弃渣量大带来的环保和经济性问题，适用于需要双向挡水、防渗防洪的抽水蓄能电站上、下水库的设计施工。
