Concrete face rockfill dam soft foundation reinforcing structure and construction method
The invention discloses a concrete face rockfill dam soft foundation reinforcing structure and a construction method. The concrete face rockfill dam soft foundation reinforcing structure comprises a geogrid reinforced cushion layer, a geocell reinforced cushion layer and gravel piles which are arranged in a dam body; the top ends of the gravel piles are fixedly wrapped with composite geotextiles, and the gravel piles extend into a soft foundation; a dam body filler is arranged on the top layer of the soft foundation; and a concrete face is arranged on the surface layer of the dam body filler, the bottom end of the concrete face is connected with a concrete connecting plate, a concrete anti-seepage wall is arranged at the bottom of the tail end of the concrete connecting plate and extends into the soft foundation, and an anti-seepage curtain is arranged at the bottom of the concrete anti-seepage wall. The differential settlement deformation of the earth and rockfill dam can be effectively controlled, the possibility of foundation liquefaction is reduced, and the stability of the earth and rockfill dam is improved.
本发明公开了一种混凝土面板堆石坝软弱地基加固结构及施工方法，它包括设置在坝体内部的土工格栅加筋垫层、土工格室加筋垫层和碎石桩；所述碎石桩的顶端包裹固定有复合土工织物，所述碎石桩伸入到软弱地基；所述软弱地基的顶层为坝体填料；所述坝体填料的表层设置有混凝土面板，所述混凝土面板的底端与混凝土连接板相连，所述混凝土连接板的末端底部设置有混凝土防渗墙，所述混凝土防渗墙伸入到软弱地基，所述混凝土防渗墙的底部设置有防渗帷幕。能有效的控制土石坝的不均匀沉降变形，降低地基液化发生的可能性，提高了土石坝的稳定性。
