摘要
长江上游水库群联合防洪调度事关流域防洪安全和长江经济带建设。为进一步减少长江中下游总体防御对象1954年洪水的超额洪量,以最新长江上游水库群联合防洪调度方案和水库群多区域协同防洪调度模型为基础,综合考虑上游水库群配合方式、三峡水库防洪调度方式、中下游防洪调度控制条件和三峡库区回水安全,基于不同的研究视角和优化思路,提出了长江上游水库群配合模式下三峡水库防洪调度方式优化策略,包括继续对城陵矶防洪补偿的调度策略、优化对荆江防洪补偿的调度策略、考虑库区回水淹没影响的调度策略。研究结果表明:提出的3种优化调度策略实用有效,均可有效减少1954年长江中下游超额洪量10%以上,可为长江大洪水防御的实时优化调度和调度方案编制提供思考建议和决策参考。
The joint flood control operation of the giant reservoirs in the upper reaches of Changjiang River plays an important role in the safety of Changjiang River Basin and the construction of Changjiang River Economic Belt.In order to further reduce the excess volume of 1954 flood,a typical flood control object for Changjiang River,based on the current joint flood control operation scheme and the multi-regional coordinated flood control operation model of reservoir groups,under comprehensive consideration on the coordination mode of reservoirs in the upper reaches of Changjiang River,the flood control operation of Three Gorges Reservoir(TGR),the flood control conditions in the middle and lower reaches of Changjiang River and the backwater safety of TGR,different optimal operation strategies of joint flood control operation of reservoir groups with TGR as a core were accordingly put forward with different research perspectives.The three flood control strategies are a strategy of still conducting supplementary flood control for the Chenglingji area,a strategy of flood control for Jingjiang reach and a strategy of considering backwater impact.The calculation results indicated that the proposed three strategies are practical and effective for effectively reducing the excess flood volume of 1954-type flood by more than 10%,so as to provide thinking,suggestions and decision-making reference for real-time flood control operation and operation scheme preparation of Changjiang River flood prevention.
