【摘要】 受2305号台风“杜苏芮”北上影响，2023年7月29日至8月2日京津冀地区连续降雨，海河流域发生“23·7”流域性特大洪水，造成严重的人员伤亡和财产损失。对北京市境内拒马河进行洪水调查，在深入分析拒马河治理现状的基础上，采用天然河道恒定流水面线计算和均匀流计算方法推求洪痕对应的流量，并以此复盘分析洪水频率。根据洪水分析成果及水毁情况，从拒马河水域空间划定、河道治理及建筑物设计等方面提出规划治理建议，以期为后续河道整治提供参考。更多还原

【Abstract】 Affected by Typhoon "Doksuri" heading north, continuous rainfall occurred in the Beijing-Tianjin-Hebei region from July 29 to August 2 of 2023, resulting in a "23·7" catastrophic flood in the Haihe River Basin, causing serious casualties and property damage. This article conducts a flood investigation on the Juma River in Beijing, and based on a thorough analysis of the current situation of Juma River treatment, mainly uses the calculation method of natural river constant flow surface line and uniform flow to calculate the flow rate corresponding to flood marks and review the Juma River floods and analyze the frequency of this flood. Based on the results of flood analysis and the situation of flood damage, planning and treatment suggestions are proposed from the aspects of spatial delineation of the Juma River water body, river regulation, and building design, providing reference for subsequent river regulation.更多还原
