| 摘 要： | 三峡工程蓄水运用后,随着蓄水位的逐步抬高,库区水深增加,对航道尺度、航行条件起到直接的改善作用。然而,水沙条件和边界条件的重大变化也将使大坝上游河段的水流条件、冲淤特性及河床演变规律发生变化,并可能使部分滩险的航道条件趋于恶化,或造成新的碍航滩险。文章利用三峡工程蓄水后2003～2008年航道原型观测资料,在对坝上河段的水沙条件变化总结认识的基础上,重点分析了三峡工程蓄水后坝上河段航道条件变化特点。 |

| Abstract: | After water storage,as storage water level gradually raising and water depth of reservoir region increasing,the waterway dimensions and the navigation condition are improved directly.However,the major changes of water-sand and boundary conditions will also make the variation of flow conditions,scouring and deposition characteristics and river-bed evolution law.Meanwhile,it will probably deteriorate the waterway condition of some rapids and shoals,even probably cause new rapids and shoals of impeding navigation.In this paper,the prototype measurement data during 2003～2008 after water storage of the Three Gorges Project were analyzed.Based on the summarized cognition of water-sand variation at upstream sections of the Three Gorges Project,variation characteristics of waterway condition at upstream sections after water storage were mainly analyzed.It has a significance to understand variation characteristics of waterway condition and regulate rapids and shoals of impeding navigation. |
