【摘要】 以长江口深水航道治理一期工程实施前后的水文同步测验资料、浮泥观测分析资料、水下地形测量资料以及航槽回淤统计资料等为依据,首次对北槽深水航道一期工程实施前后最大浑浊带的分布规律进行系统总结和分析,研究评价了北槽最大浑浊带的分布对北槽航槽淤积和拦门沙地形发育的影响,研究成果可为北槽深水航道治理二、三期工程的顺利实施提供参考,同时澄清一些认识。更多还原

【Abstract】 Based on the current and suspended sediments data, fluid mud, relief maps of sea bed, siltation along navigation channel, etc., the change and distribution of maximum turbidity along North Passage before and after the Construction of the first stage of Yangtze Estuary Deepwater Channel Regulation Project and its influence on the sedimentation along navigation channel in North Passage are summarized and studied in this paper. In addition, the change of mouth bar in North Passage before and after the construction is summarized and its future evolution is studied. The results can provide a valuable reference for the Construction of the Second and Third stage of Yangtze Estuary Deepwater Channel Regulation Project and some arguments on such problems as the evolution of maximum turbidity in North Passage and the effect of the first stage of Yangtze Estuary Deepwater Channel Regulation Project on the change of mouth bar, etc., are clarified.更多还原
