典型分汊河段航道整治鱼骨坝工程设计方法

鱼骨坝作为一种类型的整治建筑物,在长江中下游分汊河段航道整治工程中发挥着重要的作用。戴家洲河段为长江中下游一较为典型的分汊河段。以该河段航道整治为例,介绍鱼骨坝工程设计方案,归纳总结鱼骨坝设计方法和有关参数选取原则,对深入认识鱼骨坝在分汊河段航道整治中的作用具有重要意义,同时可为类似河段航道整治中采用鱼骨坝提供设计参考。

Design methods of fishbone dike engineering for channel regulation of typical braided river section

As a type of regulation structure, fishbone dike exerts an important role in channel regulation works of the middle and lower Yangtze River. Daijiazhou river section is a typical braided section on the middle and lower Yangtze River. Based on the channel regulation project of Daijiazhou river section, this paper describes the design scheme of fishbone dike works, and summarizes the methods and parameters-selecting of design of fishbone dike, which is of far-reaching importance to make an in-depth realization on the application of fishbone dike in the channel regulation of a braided river section, and can provide a design reference for fishbone dike adopted in the channel regulation of similar river sections.
