摘　　要：兰家沱水道浅碛子浅滩受周边复杂的通航环境制约,开展维护疏浚较为困难。在分析研究河段维护实施的难点后,提出合理的疏浚方案,并根据黄泥湾水尺水位近年来的变化过程,提出将疏浚施工时间由枯水期提前至中水期,同时对施工期航道布置、抛泥位置及施工顺序进行优化,实现非禁航施工。根据方案的实施效果,施工质量满足设计要求,工期由预期的30 d缩短为23 d,在保障正常的航道经济效益的同时,降低施工成本。Maintaining and dredging the shallow reefs and shoals in the Lanjiatuo Waterway are difficult due to the complex navigation environment.This paper proposes a reasonable dredging scheme after analyzing the difficulties in implementing maintenance in the research section.According to the process of changes in water levels in the Huangniwan gauge in recent years,this paper advocates advancing the dredging construction time from the dry season to the middle water period.The paper also optimizes the layout of the channel during the construction period,the mud throwing position,and the construction sequence,so as to achieve non-prohibited navigation during construction.Based on the implementation effect of the scheme,the construction quality meets the design requirements,and the construction period is shortened from the expected 30 days to 23 days.While ensuring the normal economic benefits of the waterway,the dredging scheme also reduces the construction costs.
