水下崩岸段吨袋垫坡与膜袋自密实混凝土护坡施工技术应用与效果分析

河道的回水地带常年受河道水流迎流顶冲影响，岸坡冲刷严重易崩塌，影响岸坡安全。以涡河县义门镇涡河左堤崩岸段应急加固工程为例，采用吨袋垫坡+膜袋自密实混凝土护坡技术对崩岸段进行加固处理有效解决了水下护岸边坡因水流冲刷引起的变形与坍塌问题，效果良好，可为类似工程施工提供参考。

Application and effect analysis of ton bags mat slope and membrane bag self-compacting concrete slope protection construction technology in subaqueous revetment

The backwater zone of the river channel is constantly influenced by upstream counter-current scour, resulting in severe erosion and a high risk of slope collapse, which impacts the safety of the riverbank. Taking the emergency strengthening project of the left embankment of the Guohe River in Yi-men Town, Guohe County as an example, the technology of ton bags mat slope + membrane bag self-com-pacting concrete slope protection is adopted to strengthen the embankment section, which effectively solves the deformation and collapse problem caused by water erosion of the underwater bank protection slope. This reinforcement method has proven to be highly effective, and related research can serve as a reference for similar engineering construction projects.
