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.
