Earth and rockfill dam capable of preventing overtopping damage
The invention discloses an earth and rockfill dam capable of preventing overtopping damage, which comprises an upstream protection slope, an upstream side dam body, a wave wall, a dam crest road surface, a core wall, a concrete base, a curtain, a downstream side dam body, a downstream handrail and a downstream riverbed surface, and cement blankets are laid under the dam crest road surface and on the downstream side dam surface, so that the anti-scouring capability of the downstream side dam body is improved; a self-compacting stone-buried concrete retaining wall protection foot is arranged on the downstream of the dam body, and a downstream slope toe is connected with the self-compacting stone-buried concrete retaining wall protection foot in a reverse arc section mode, so that washing damage is prevented. And a riprap apron can be made on the downstream side of the self-compacting embedded stone concrete retaining wall protection foot. The anti-scouring capacity of the dam body on the downstream side is improved through the cement blanket, and then the self-compacting buried stone concrete retaining wall protection foot is adopted on the downstream of the dam body to prevent scouring damage. The dam break caused by overtopping damage is effectively avoided, and the method is particularly suitable for dams with multiple cascade reservoirs.
本发明公开了一种防止漫顶破坏的土石坝，包括上游护坡、上游侧坝体、防浪墙、坝顶路面、心墙、混凝土基座、帷幕、下游侧坝体、下游栏杆、下游河床面，在坝顶路面下面和下游侧坝体坝面上铺设有水泥毯，提高下游侧坝体防冲刷能力，在坝体下游设置自密实埋石混凝土挡墙护脚，下游坡脚采用反弧段形式与自密实埋石混凝土挡墙护脚相连，防止淘刷破坏。可在自密实埋石混凝土挡墙护脚下游侧做抛石海漫。本发明利用水泥毯提高下游侧坝体防冲刷能力，然后在坝体下游采用自密实埋石混凝土挡墙护脚防止淘刷破坏。本发明有效避免因漫顶破坏造成的溃坝，尤其适用于有多个梯级水库的坝。
