| 摘 要： | 闽侯县小目溪一级水库电站拦河坝是双曲砌石拱坝,前期砌体砌筑振捣不充分,坝体内裂缝、孔隙发育错综复杂,补强灌浆很难达到满意的处理效果。通过采取降低灌浆压力、增浓浆液、表面封堵、待凝、环丙砂浆嵌缝、间歇灌浆等三阶段法综合处理方案措施,该工程补强灌浆取得了较好的效果。

| Abstract: | Minhou County Xiaomuxi Level I reservoir power station barrage belongs to hyperbolic masonry arch dam.The masonry building is not sufficiently vibrated at early stage.The crack and holes in the dam are developed complexly.Reinforcement grouting of the project achieved better effect by comprehensive treatment measures of three-stage methods,namely,reduction of grouting pressure,slurry concentration increase surface sealing,condensation waiting,cyproterone mortar caulking,intermittent grouting and the like. |
