山地城市市政基础设施内涝风险识别及防治能力评估

本研究以立交下穿道、轨道交通、隧道3类市政基础设施为研究对象，分析总结山地城市市政基础设施的致涝因子，结合重庆市中心城区历史积水情况，运用现场调查、文献调研等多种风险分析方法，构建了山地城市重要市政基础设施内涝防治能力3级评估方法，旨在快速评估位于低洼区域的重要市政基础设施内涝防治能力，为后续内涝积水整改工作提供技术与数据支撑。针对高风险设施采用水力模型法校核内涝风险，中风险设施采用推理公式法校核，低风险设施无需校核。

Identification of Waterlogging Risk and Assessment of Prevention Capacity for Municipal Infrastructures in Mountainous Cities

Taking three kinds of municipal infrastructures, i.e. underpass, rail transit and tunnel as the research object, the waterlogging causes of municipal infrastructures in the mountainous cities are analyzed and summarized. Combined with the historical waterlogging situation in the central area of Chongqing and by applying the multiple risk analysis methods of field investigation and literature research, a three-level assessment method for the waterlogging prevention and control capacity of important municipal infrastructures in mountainous cities is constructed, which aims to quickly evaluate the waterlogging prevention and control capacity of municipal infrastructures in the low-lying areas and provide the technology and data supports for the subsequent waterlogging treatment work. For the high-risk facilities, the hydraulic model method is used to check the waterlogging risks. The medium-risk facilities are checked by the reasoning formula method, and the low-risk facilities cannot be checked.
