摘要/Abstract

摘要： 渣角滩是三峡水库变动回水区的重点维护滩险，存在着有效航宽不足，船舶安全航行难度较大等问题。从2022年度的维护性疏浚技术方案、施工过程、疏浚效果、施工时机等方面出发，对渣角滩养护疏浚进行全面的分析、总结和评估。评估结果表明：渣角滩疏浚施工后，航道条件有明显改善；疏浚设计方案与河段演变规律、水位变化趋势、航道通行影响相适应；疏浚时机选择和现场动态管理合理规范。

Abstract: Zhajiao Beach is a critical maintenance area within the fluctuating backwater zone of the Three Gorges Reservoir, facing issues such as insufficient effective navigational width and large difficulty in ensuring the safe passage of vessels. Starting from the maintenance dredging technology plan, construction process, dredging effects and timing of construction in 2022, a comprehensive analysis, summary and evaluation of the maintenance and dredging of Zhajiao Beach was conducted. The evaluation results show that after the dredging operations at Zhajiao Beach, the navigational conditions have a significant improvement. The dredging design plan is well-adapted to the evolutionary patterns of the river section, variation trends of water level and traffic impacts on navigation channel. And the choice of dredging timing and dynamic onsite management are reasonable and standardized.

Key words: waterway engineering; maintenance dredging; fluctuating backwater area; dredging plan
