三峡库区碍航滩险龙王沱河段通航条件试验及整治措施的初步研究

The preliminary research on navigable conditions and regulation measurements of Longwangtuo reach in Three Gorges reservoir district

根据重庆涪陵河段水工模型试验成果，分析了龙王沱河段在三峡水库不同运行时段龙王沱河段的泥沙淤积与通航水流条件的变化，在此基础上，提出了龙王沱河段的整治措施及整治工程的初步布置方案，为下一阶段龙王沱碍航滩险的整治工程设计提供依据．

Longwangtuo, lying in the reach of Fuling central harbour area, is known as one of the navigation-hampering shoals. This paper analyses the changes of the sediment despite and navigable new conditions in various run times of Three Gorges reservoir in Longwangtuo reach, resulted from the achievements of the hydraulic model experiments in Fuling reach. On basis of this, it puts forward to the river regulation measurements and the preliminary scheme of the regulation engineering, which presents the fundamental proof for the regulation engineering design of Longwangtuo navigation-hampering shoal at the next step.
