某大比降卵砾石河床堤防护脚加固型式选择

Selection of Reinforcement Types for Embankments in A Larger than Gravel Bed

以西藏某河道堤防加固工程项目为例,针对该典型大比降卵砾石河床河流特点,提出堤防堤脚加固方案,并进行抗冲能力、施工、造价的比选,最终推荐一种适合该河段特点的加固结构型式,可供类似河段整治工程的设计参考。

Taking a river embankment reinforcement project in Tibet as an example, according to the characteristics of the typical large gradient gravel bed river, this paper puts forward the reinforcement scheme of the embankment foot, compares and selects the anti scour capacity, construction and cost, and finally recommends a reinforcement structure type suitable for the characteristics of the river section,which can be used as a reference for the design of similar river regulation projects.
