| 摘 要： | 在收集三峡与丹江口水库下游河道河型研究成果基础上，总结与分析了三峡与丹江口水库下游河道不同河型的成因，包括来水来沙条件，河道边界条件和比降变化。结果表明，丹江口水库建成运用后，汉江中游河道演变为相对稳定的分汊或单一河道，下游弯道发生撇弯切滩；三峡水库建成运用后，下游河道的变化程度要小于汉江下游。指出了三峡水库下游河道河型变化的复杂性，及需要进一步研究的课题，研究成果可供大型水利枢纽工程下游河道河型变化机理研究参考。

| Abstract: | Based on the existing research results of river pattern in the downstream of Three Gorges and Danjiangkou reservoirs,the formations of different river patterns are summarized and analyzed,including incoming flow and sediment condition,boundary condition of river channels and gradient ratio.It is concluded that after completion of Danjiangkou Reservoir,the river channel of middle Hanjiang River changes into a stable braided or single channel and the bend bypassing and shore cutting occur in the lower reach;a... |
