| 摘 要： | 根据实测资料,应用泥沙最大粒径dmax及中值粒径d50的变化规律,对三峡水利枢纽坝下游河段床沙、悬沙组成及其蓄水后变化分河段进行统计分析。从洲滩组成、水下床沙、悬沙的变化来看,三峡蓄水后该河段泥沙有粗化现象。

Analysis on Sediment Components in Jingjiang River Reach in Downstream of Three Gorges Dam |

| Abstract: | By using the change rules of the maximum sediment particle size dmax and the median particle size d50,the statistical analyses are made here for the component as well as the changes of the bed sand load and suspended sand load in different reaches of Three Gorges Dam's downstream river bed according to the measured data.Through researching on the component of the continent beach and the changes of the bed sand load and suspended sand load,it is shown that after storing water in the Three Gorges Dam,the sediment in this reach has coarsened. |
