%X 在城市内涝问题日益加剧的大背景下，以武汉东沙湖流域作为研究对象，基于InfoWorks ICM构建排水管网数学模型。通过对各类基础数据的深度整合实现模型的合理概化，并采用特定降雨资料达成模型参数的精确率定。依据现状及规划要求，选取不同降雨工况模拟东沙湖流域内涝风险。研究结果表明，遭遇20年一遇降雨时内涝风险基本处于可控范围，而面临100年一遇降雨时则涌现出较多中高风险区域。进一步针对水果湖片成果展开精细化剖析，梳理出关键防护对象并绘制内涝主题风险图，为水果湖片内涝防御工作提供了更为精准的指导。
In the context of the increasingly severe urban waterlogging problem, this study takes the Dongsha Lake Basin in Wuhan as the research object and uses InfoWorks ICM to build a mathematical model of the drainage pipe network. Through the in-depth integration of various basic data, the reasonable generalization of the model is realized, and the specific rainfall data is used to achieve the accurate calibration of the model parameters. According to the current situation and planning requirements, different rainfall conditions are selected to simulate the waterlogging risk in the Dongsha Lake Basin. The results show that when encountering the 20-year return period rainfall, the risk is basically controllable, while when facing the 100-year return period rainfall, more medium and high-risk areas emerge. Further, a detailed analysis of the results of the Fruit Lake area is carried out, the key protection objects are sorted out, and the thematic risk maps are carefully prepared, providing more accurate guidance for the waterlogging prevention work in the Fruit Lake area.
