三峡库区涪陵港区码头对长江涪陵段防洪的影响分析

Influences of Fuling dock in the Three Gorges Reservoir area on flood control of Fuling reach

  • 摘要: 在分析长江涪陵段的水沙特性和三峡水库蓄水前后该河段河床演变趋势的基础上,运用二维水流数学模型,分析了4种流量组合情况下在三峡水库运用前和运用50年,涪陵港区码头修建前后的水位、流速变化及其影响范围.结果表明,修建涪陵港区码头对该河段的防洪及河势变化影响不大.

     

    Abstract: Based on the analyses of the flow and sediment characteristics and evolution trend of the river bed of the Fuling reach in the Yangtze River before and after the impoundment of the Three Gorges Reservoir,the water level,velocity variation and influenced range in the Fuling reach before and fifty years after the operation of the Three Gorges Reservoir with the construction of the Fuling dock and four discharge combinations are calculated by using a two-dimensional flow mathematic model.Results show that the construction of the Fuling dock has a little influence on flood control and flow regime of the Fuling reach.
