基于Mike模型的海绵城市内涝整治方案效果分析
|
摘要
通过Mike水动力模型,建立了玉溪市老城片区固定径流模型。根据2016年7月20日玉溪市实测降雨情况,对模型中节点溢流和地面淹没情况进行定量模拟,并将模型积水点深度与实际积水点深度进行对比,验证了模型适用性。利用模型对30年一遇、24 h降雨情况下的玉溪市老城片区进行了分析,总结了内涝积水点出现的原因,并提出了内涝整治方案。实施整治后的老城片区积水深度降低,内涝点基本清除。
Based on Mike hydrodynamic model,the fixed runoff model of Yuxi old town was established. According to the actual rainfall measured in Yuxi City on July 20,2016,the overflow of nodes and ground inundation in the model were quantitatively simulated,and the accumulation water depth of model was compared with the actual depth to verify the applicability of the model. According to the modelling results of Yuxi old town under 24 h rainfall once in 30 years,the reasons of local waterlogging was summarized. A renovation scheme for preventing waterlogging was proposed. It was found that after renovation,the regional accumulation water depth was reduced and waterlogging points were basically cleared.
