北京“23·7”特大暴雨洪水期间十三陵水库闸门调度分析

Analysis of gate operation of the Ming Shisanling-Tombs Reservoir during the "23·7" extremely heavy rainstorm flood in Beijing

2023年7月29日至8月2日,受2305号台风“杜苏芮”影响,北京市遭遇历史罕见特大暴雨,全市水利工程设施面临严峻考验,十三陵水库流域也发生超标准洪水。为保障水库及下游防洪安全,水库管理处按照洪水调度方案及上级指示要求,组织专业技术人员对水库闸门进行准备检查、开闸泄洪及流量开度控制,实施了水库近25年来首次泄洪,对洪水进行科学调度。介绍了北京“23·7”特大暴雨洪水相关情况,以及十三陵水库在洪水前、洪水期间、泄洪期间的闸门运行情况,进一步对闸门运行调度进行分析。分析表明,实现及时拦洪、错峰泄洪,在成功抵御洪水中发挥了重要作用,在防汛工作中具有参考意义。

From July 29 to August 2,2023,under the influence of Typhoon 2305 "Doksuri",Beijing suffered a rare extremely heavy rainstorm in history,the city's water facilities faced severe tests,and the Ming Shisanling-Tombs Reservoir basin also suffered from beyond-standard designed floods.In order to ensure the safety of the reservoir and downstream,the reservoir management department organized professional technical personnel to prepare and inspect the reservoir gate,open the gate for flood discharge,and control the flow opening in accordance with the flood scheduling plan and superior instructions.The first flood discharge of the reservoir in nearly 25 years was implemented,and the scientific scheduling of the flood was carried out.By the Introduction of the relevant situation of the "23.7" watershed catastrophic flood,as well as the gate operation of the Shisanling Reservoir before,during,and during the flood discharge period,and the gate operation and scheduling are further analyzed.Analysis shows that timely interception and staggered flood discharge have played an important role in successfully resisting floods and have reference significance in flood work.
