Counterfort type retaining wall sand gravel mixed dam
The invention discloses a counterfort type retaining wall sand gravel mixed dam in the technical field of water conservancy and hydropower engineering, which comprises a concrete retaining wall, the concrete retaining wall comprises a retaining wall panel, a retaining wall bottom plate, a counterfort and upstream backfill sand gravel, and the upstream backfill sand gravel is backfilled on a toe board part of the retaining wall bottom plate on the upstream side of the concrete retaining wall; the downstream backfill sand gravel is backfilled on the heel slab part of the retaining wall bottom plate on the downstream side of the concrete retaining wall; and the protection slope covers the downstream backfilled sand gravels and the buttress. The mode that the earth and rockfill dam and the concrete dam are combined is adopted, the anti-sliding stability of the concrete retaining wall is enhanced through the ballasting effect of the backfilled sand gravels on the retaining wall bottom plate, sedimentation of the backfilled sand gravels is prevented through the bearing effect of the retaining wall bottom plate on the backfilled sand gravels, and the stability of the retaining wall is improved. The dam body structure of the mixed dam has the advantages of an earth and rockfill dam and a concrete dam at the same time, and the crack phenomenon caused by the temperature stress of the concrete dam is avoided.
本发明公开了水利水电工程技术领域的一种扶壁式挡墙砂砾石混合坝，包括混凝土挡墙，混凝土挡墙包括两两垂直连接的挡墙面板、挡墙底板和扶壁，上游回填砂砾石，上游回填砂砾石回填于混凝土挡墙的上游侧的挡墙底板的趾板部上；下游回填砂砾石，下游回填砂砾石回填于混凝土挡墙的下游侧的挡墙底板的踵板部上；护坡，护坡覆盖于下游回填砂砾石和扶壁上。本发明采用土石坝和混凝土坝向结合的方式，通过回填砂砾石对挡墙底板的压载作用增强混凝土挡墙的抗滑稳定性，通过挡墙底板对回填砂砾石的承载作用，防止回填砂砾石的沉降，使得混合坝的坝体结构同时具有土石坝和混凝土坝的优点，并避免了混凝坝温度应力导致的裂纹现象。
