摘要
针对三峡水库来水来沙减少、上游水库陆续建成运行、下游防洪及需水要求提高等不断出现的新情况,不同时期三峡水库采取了不同的运行调度方式。为了总结三峡水库的调度运行经验,为今后三峡水库优化调度提供依据,分析了不同调度方式对防洪、泥沙等方面的影响。分析表明:为应对新情况而相应调整的调度方式在不降低荆江防洪标准的前提下,可更好地兼顾城陵矶和荆南四河地区的防洪任务,在对泥沙淤积影响有限的同时,可更好地发挥抗旱、供水、航运、发电等综合利用效益。
In the light of new situations of incoming flow and sediment decreasing,upstream reservoirs being built and running successively,increasing requirements of the downstream flood control and water demand,different operation and regulation modes are adopted for the Three Gorges Reservoir in different stages. In order to summarize the reservoir operation experiences and provide basis for optimizing the reservoir regulation,the achievements in flood control,water supply,power generation and the influence on sediment scouring and silting under different regulation modes are analyzed. The analysis results show that under the premise of not lowering the flood control standard of Jingjiang River,the new regulation mode that is adjusted for the corresponding changes,can better balance the flood control of Chenglingji and 4 rivers in the south of Jingjiang River,and obtain better comprehensive benefits of drought fighting,water supply,navigation,power generation with smaller influence on sedimentation.
