Earth and rockfill dam crest anti-seismic structure and construction method thereof
The invention provides an earth and rockfill dam crest anti-seismic structure which is characterized in that a reinforcement arrangement area is arranged from the upper area of a dam main body to the inside of a dam crest, reinforcement nets are laid in an upstream dam body and a downstream dam body in the reinforcement arrangement area, and the reinforcement nets are provided with interval spaces in the vertical filling direction of the dam main body; a first anchoring pier is arranged on a connecting node of the reinforcing steel bars in the reinforced net, is divided into an upper consolidation part and a lower consolidation part through the reinforced net, and is used for forming layered consolidation with a filling body in the dam main body; an anti-seismic grid beam is arranged on the downstream dam face of the dam body. The first anchoring piers of the reinforced net nodes are used for improving the restraining effect between the reinforced net and the rock-fill body, and the integrity and the anti-seismic property of the rock-fill body in the reinforced arrangement area are improved; and moreover, the engineering quantity is small through the reinforced net, the anti-seismic effect can be remarkable, the appearance control requirement on the anchoring pier basically does not exist, and the construction is simple and easy.
本发明提供了土石坝坝顶抗震结构，在大坝主体的上部区域至坝顶内设置加筋布置区，所述加筋布置区在上游坝体和下游坝体内皆平铺设置加筋网，所述加筋网在大坝主体填筑的竖向方向上设置有间隔空间，且所述加筋网内部钢筋的连接节点上设置第一锚固墩，所述第一锚固墩通过加筋网将其分为上固结部和下固结部，用于与大坝主体内部的填筑体形成分层固结；所述大坝主体的下游坝面设有抗震网格梁。本发明利用加筋网节点的第一锚固墩提高加筋网和堆石体之间的约束作用，提高加筋布置区堆石体的整体性和抗震性能；而且通过该加筋网工程量少、所能达到的抗震效果显著，且对锚固墩基本无外观控制要求，施工简易。
