摘要
长江中游天兴洲河段为位于武汉主城区的分汊河段,航道条件不稳定,影响航运畅通。文章根据天兴洲河段近年来实测水文和地形资料,分析了该河段河床演变特点及趋势,揭示了碍航特性;结合平面二维水沙模型研究成果,提出了航道整治思路和治理方案,为类似河段航道整治提供参考。
Tianxingzhou reach is flowing through the main city of Wuhan which located at the middle Yangtze river. It is a braided reach, leading to unstable waterway condition, impacting shipping industry severely. Based on topographic and hydrologic data recorded recently years, characteristics and tendency of river bed evolution were analyzed. Furthermore, along with the two-dimensional model, the regulation thoughts and approach of waterway were proposed. This study provides reference material to channel regulation of braided reach.
