装配式空箱生态护岸在高流速河道防护工程中的应用

Application of Assembly Ecological Empty-box Revetments in Protection Projects for Rivers with High Flow Rate

针对传统生态护岸抵抗高流速洪水冲刷能力较差的现状,提出装配式空箱生态护岸这一在水利工程领域尚未应用的新形式。通过抗冲刷稳定计算确定抗冲尺寸要求,并对不同形式的构件尺寸、生态效果等进行比选,结果表明:装配式空箱护岸形式在高流速生态型河道治理中优势明显,既能满足抗冲流速要求,又兼具生态效果。结合朝阳市十家子河城区段综合治理工程,对装配式空箱护岸方案进行比选,最终确定生态景观效果更好的阶梯式方块结构,并对其进行设计。装配式空箱生态护岸形式值得在水利工程领域推广,可为高流速生态型河道的治理方案研究提供新的方向。

In response to the poor resistance of traditional ecological revetments to flood erosion with high flow rate,the article proposed a new type of assembly ecological empty-box revetments that had not yet been applied in the field of water conservancy engineering.The required anti-erosion size was determined through calculation,and different types of components were compared through sizes and ecological effects.The results showed that assembly ecological empty-box revetments had obvious advantages in the field of ecological rivers with high flow rate.It can not only resist floods with high flow rate,but also possesses ecological effects.Based on the Comprehensive Treatment Project of Shijiazi River in Chaoyang,this article proceeded further comparison of assembly ecological empty-box revetments.Ultimately,a type of stepped block structure was adopted and designed,which had better ecological landscape effects.Assembly ecological empty-box revetments are worthy of widespread promotion in the field of water conservancy engineering,which can provide references for the study of treatment schemes for ecological rivers with similar high flow rates.
