Asphalt concrete core wall rock-fill dam partition structure
The invention belongs to the technical field of water conservancy projects, and particularly discloses an asphalt concrete core wall rock-fill dam partition structure which is characterized in that a dam body is divided into an upstream rock-fill material area, an upstream transition material area, an asphalt concrete core wall material area, a downstream inverted filter transition material area and a downstream rock-fill material area from upstream to downstream; the asphalt concrete core wall material area comprises a core wall anti-seepage body, and the core wall anti-seepage body is gradually enlarged from top to bottom and then is connected with the concrete base; the upstream transition material area and the downstream transition material area are perpendicularly arranged on the two sides of the core wall anti-seepage body respectively. The downstream dam base face of the dam body is further provided with a drainage belt, and a reversed filter material layer is arranged between the drainage belt and the downstream rockfill material area. Local materials can be conveniently used as filling materials, the performance requirement for damming filling materials is lowered, the formed dam body can effectively improve the moderate deformation degree of the dam body after water storage, normal operation of the dam is guaranteed, and the investment of dam construction is reduced.
本发明属于水利工程技术领域，具体公开了一种沥青混凝土心墙堆石坝分区结构，所述坝体从上游至下游分为上游堆石料区、上游过渡料区、沥青混凝土心墙料区、下游反滤过渡料区和下游堆石料区；所述沥青混凝土心墙料区包括心墙防渗体，所述心墙防渗体从上至下渐变式增大后与混凝土基座连接；所述上游过渡料区和下游过渡料区分别垂直布置于心墙防渗体的两侧；所述坝体的下游坝基面还开有排水带，所述排水带与下游堆石料区之间设有反滤料层。本发明便于就地取材作为填筑料，降低了对筑坝填筑材料的性能要求，完成的坝体能有效提高蓄水后坝体的变形适度，保证大坝的正常运行，减少了大坝修建的投入。
