Abstract: Construction at low water season, stand-down at flood season is a tradition that we use to dredge up the river, but dredging up Tonggu and Saojibei Shoal at flood season has received good treatment effect in the treatment project of Xu- Lu section.Based on the received achievements, the design methods of dredging up river at flood season are discussed, through analyzing the resolutions to difficulties occurring in the engineering construction.The design methods include the key of designing at prophase, the arrangement of working procedure, and the determinant of the adaption of dredge up at flood season etc.Therefore, references are offered to the design method of dredging up the similar shoal in the upper Changjiang River at flood season.

摘要： 川江疏浚传统采用枯期施工,汛期停工作业方式,在叙泸段整治工程铜鼓滩、筲箕背滩的整治中采用汛期疏 浚施工,取得了良好效果。在此基础上,通过研究分析工程实施中出现的困难和解决方法,对汛期疏浚在前期设计 要点、施工工序安排、是否汛期疏浚的判定等疏浚设计方法进行了探讨,这对长江上游类似滩段的汛期疏浚设计提 供了一定借鉴。
