摘　　要：以牯牛沙水道为例,重点分析了弯曲河段的演变过程和碍航特点。通过分析牯牛沙水道的演变过程、演变影响因素、演变趋势及碍航特性等,揭示滩槽演变的规律,探讨航道整治一期工程前后的碍航特性变化,并对一期工程实施后航道条件不稳定的具体原因进行分析,在此基础上,提出二期工程的整治思路和方案。Taking Guniusha waterway as an example, the fluvial processes and navigation obstruction problem of curved reaches were emphasized in this paper. The fluvial processes, influencing factors, tendency of channel variation of Guniusha waterway, the characteristics of navigation-obstruction and causes of instability in channel conditions after implementing the 1st phase regulation projects were mainly analyzed and studied. Based on the above-mentioned analysis, the 2nd phase regulation scheme was proposed in order to provide references for engi- neering practice.
