Arrangement structure and construction method of asphalt concrete core-wall rock-fill dam
The invention relates to an arrangement structure and a construction method of an asphalt concrete core-wall rock-fill dam. The invention aims to provide the arrangement structure and the constructionmethod of the asphalt concrete core-wall rock-fill dam, so as to improve the foundation adaptability of the asphalt core-wall rock-fill dam, reduce the requirements on the performance of a damming material, and improve the safety and the economy of the asphalt concrete core-wall rock-fill dam. The technical scheme of the invention is as follows: the arrangement structure of the asphalt concrete core-wall rock-fill dam is characterized in that a dam body of the asphalt concrete core-wall rock-fill dam is arranged in an arch shape protruding towards the upstream, and the dam axis of the dam body is formed by two sections of arcs with the radiuses of R1 and R2 respectively, which are tangent in the middle of a riverbed; the arc, which is connected with a bank slope part with a steep bank slope and a deep covering layer, in the two sections of arcs of the dam axis adopts a smaller arc radius, and the arc, which is connected with a bank slope part with a relatively gentle covering layer and a relatively shallow covering layer, adopts a relatively large arc radius; and when the symmetry of topographic and geological conditions of both banks is better, the arc radius R1 is equal to R2.
本发明涉及一种沥青混凝土心墙堆石坝布置结构及施工方法。本发明的目的是提供一种沥青混凝土心墙堆石坝布置结构及施工方法，以提高沥青心墙堆石坝的地基适应性和，降低对筑坝材料性能的要求，提高沥青混凝土心墙堆石坝的安全性和经济性。本发明的技术方案是：一种沥青混凝土心墙堆石坝布置结构，其特征在于：该沥青混凝土心墙堆石坝坝体采用凸向上游的拱形布置，坝体的坝轴线由两段半径分别为R1和R2的圆弧在河床中部相切形成；所述坝轴线的两段圆弧中与岸坡陡、覆盖层深的岸坡部位相连的圆弧采用较小的圆弧半径，与相对缓、覆盖层相对浅的岸坡部位相连的圆弧采用相对较大的圆弧半径；当两岸地形地质条件对称性较好时，圆弧半径R1等于R2。
