窑监河段为长江中游著名的碍航河段,根据《长江干线航道发展规划总体纲要》,该河段2020年航道的建设标准为3.5 m×150 m×1 000 m(水深×航宽×弯曲半径),通航保证率为98%。考虑到三峡工程运行以及防洪等外部因素的影响,窑监河段的治理采取远近结合、分期实施的原则,从2009年初开始陆续实施一期工程和乌龟洲守护工程。工程实施以来,航道条件明显改善,取得了较好的工程效果。结合已有研究成果和工程实施以来的资料,对工程实施后的河道变化、航道条件等进行分析,并对该河段治理经验进行总结。 相似文献

沙市河段为长江中游著名的碍航河段,根据《长江干线航道发展规划总体纲要》,该河段2020年航道的建设标准为3.5 m×150 m×1 000 m(水深×航宽×弯曲半径),通航保证率为98%。考虑到三峡工程运行以及防洪等外部因素的影响,沙市河段的治理采取系统治理、分步实施的原则进行,从2009年初开始陆续实施一期工程和腊林洲守护工程,工程实施以来,航道条件明显改善,取得了较好的工程效果。本文结合已有研究成果和工程实施以来的资料,对工程前后的河道变化、航道条件等进行了对比分析,并结合总体治理思路及本河段存在的问题,提出了后续治理思路。 相似文献

为更好地指导航道管理维护工作,促进航运发展,介绍嘉陵江航道泥沙淤积原型观测情况,从河段基本情况、水沙特性、冲淤量及淤积变化、深泓剖面冲淤变化等4个方面进行原型观测分析。结果表明:嘉陵江河道受水库回水影响,末端形成淤积造成航道中的水深不够而碍航,或者因河底床沙运动剧烈形成沙坡而突然碍航。结合嘉陵江河段的冲淤分布确定重点碍航段,分析各段航道内冲淤情况,为以后观测治理工作提供可靠参考依据。 相似文献
