摘　　要：贵池水道为多级多分汊河道,近几年滩槽格局变化明显,形成了双槽格局,航道条件向不利方向发展。为此,对近期河床演变及碍航特性进行分析,按照限制北港发展、稳定汊道分流格局、巩固中港的主汊及主航道地位的整治思路,提出初步的航道治理方案。通过定床和动床模型试验研究,对方案效果进行对比分析。结果表明采取梳齿型护滩守护崇文洲洲头、在北港兴隆洲右槽实施护底措施的方案较优。Guichi channel is a multi-level and multi branching channel.In recent years,the beach channel pattern has changed significantly,forming a double channel pattern,and the channel conditions are developing in an unfavorable trend.This paper analyzes the recent riverbed evolution and navigation obstruction characteristics.Following the regulation idea of restricting the development of north port,stabilizing the branching pattern of branch,and consolidating the position of main branch and main channel of China port,this paper proposes a preliminary channel regulation scheme.Through the fixed bed and movable bed model test,the scheme effect is compared and analyzed,and the test results are compared.The results show that the scheme of comb-type beach protection for the head of Chongwenzhou bar and bottom protection for Xinglongzhou right channel in Beigang is better.
