Soil core wall rock-fill dam
The invention belongs to the technical field of water conservancy and hydropower engineering, and particularly discloses a soil core wall rock-fill dam which can reduce the construction work amount of inverted filter materials on the premise of ensuring the operation safety of a soil core wall. According to the soil core wall rock-fill dam, an upstream inverted filter layer is arranged in a water level variable-amplitude area between an upstream transition layer and a soil core wall, and an area, originally filled with inverted filter materials, below the water level variable-amplitude area is a local part of the upstream transition layer formed by filling transition materials. The soil core wall soil material can be protected from being eroded when the upstream water level rises and falls, fine particles in the core wall soil material are prevented from being taken away by water flow, the operation safety of the soil core wall is guaranteed, the structure is simple, construction is convenient, the inverted filter material construction work amount is effectively reduced, the construction cost is reduced, the construction efficiency is improved, and the construction period is shortened.
本发明属于水利水电工程技术领域，具体公开了一种在保证土质心墙运行安全的前提下可减小反滤料施工工程量的土质心墙堆石坝。该土质心墙堆石坝将上游反滤层设置在上游过渡层与土质心墙之间的水位变幅区域，水位变幅区域以下原填筑反滤料的区域为填筑过渡料形成的上游过渡层局部，与现有的土质心墙堆石坝相比，不仅能够保护土质心墙土料在上游水位升降时不受冲蚀，防止心墙土料中的细颗粒被水流带走，保证了土质心墙的运行安全，而且结构简单，施工方便，有效减小了反滤料施工工程量，降低了施工成本，提高了施工效率，缩短了工期。
