| 摘 要： | 对葛洲坝水利枢纽及其运行情况和河段特性进行了介绍。分析认为葛洲坝水利枢纽运行前后的入库水沙特性基本一致。探讨了库区冲淤变化特点、淤积量及其分布,冲淤过程及达到冲淤平衡的时间。对坝下游河床的冲淤过程、冲淤量、达到冲淤平衡的时间以及河床粗化,河底高程历年变化及同流量水位降低的原因、降低量及变化过程进行了分析总结。研究结果可为进一步探讨三峡水利枢纽与葛洲坝水利枢纽联合调度运用后水库泥沙淤积变化规律提供参考。

| Abstract: | The river characteristic and the operation condition of the Gezhouba hydro-project are introduced in this paper.The analysis using the measured data shows that the characteristic of the runoff and the sediment discharge after the Gezhouba hydro-project operation is as same as before.The variation laws in reservoir area,which are scour and deposit quantity,distribution and the time that achieve dynamic balance of sediment,are studied.These factor variation laws are also studied within below the dam area.The descend reasons,values and vary process of river bed elevation and water level are summarized.This result can provide reference to recognize the reservoir deposit laws when the Three Gorges is operated in conjuntion with the Gezhouba hydro-project. |
