摘要:
城市内涝问题已成为制约城市发展的重要因素，充分掌握城市内涝成因，针对性地制定防灾策略，是当前亟待解决的难题。以海口市主城区为例，基于PCSWMM软件构建一维、二维耦合内涝模型，根据多情景模拟结果，分析内涝灾害特征及分类成因，并针对性地提出组合减灾方案。结果表明，基于PCSWMM的内涝模型可提供支撑成因分析和防灾决策的可靠信息。海口市主城区积水成因主要包括降雨量超标、潮位顶托、河道和管道排水能力不足以及地势低洼和地形平坦。通过管道、河道改造结合增设蓄水池和排涝泵站的组合减灾方案可以有效缓解区域内涝。
Abstract:
Urban waterlogging has become an important factor restricting urban development, and the urgent problems to be solved include fully understanding the causes of urban waterlogging and formulating corresponding disaster prevention strategies. A one-dimensional and two-dimensional coupled waterlogging model was constructed based on PCSWMM software. According to the results of multi-scenario simulation, the characteristics and different causes of waterlogging disasters in the main urban area of Haikou City were analyzed, and a combined disaster control scheme were proposed. The waterlogging model based on PCSWMM was capable of providing reliable information to support cause analysis and disaster prevention decision-making. The causes of waterlogging in the main urban area of Haikou City mainly included excessive rainfall, tidal backwater, insufficient drainage capacity of river channels and pipelines, low lying and flat terrain. The regional waterlogging was effectively alleviated through the pipelines and river channels reconstruction in combination with the addition of reservoirs and drainage pumping stations.
