基于MIKE模型的中心城区内涝模拟及道路内涝韧性评估方法
Simulation of Central Urban Waterlogging Control and Assessment of Roads Waterlogging Resillience Based on MIKE Model
摘要
Abstract
[Objective]At present,a large number of urban central urban areas in China have the risk of waterlogging.The central urban area has the characteristics of high construction density and low drainage pipeline standard,which makes it difficult to control waterlogging.In order to formulate a scientific and effective drainage scheme,this paper evaluated the drainage capacity of typical central urban pipe network under high water level operation through simulation technology,and compared the effects of different drainage schemes to select the optimal scheme.Based on the flood model,the waterlogging resilience assessment of waterlogged roads is carried out.[Methods]Taking Bayisi road area in Hetao old urban area of Ganzhou City as an example,based on MIKE FLOOD platform,the waterlogging model was constructed by coupling one-dimensional pipe network model MIKE URBAN and two-dimensional land overflowmodel MIKE21 to simulate the waterlogging depth and waterlogging range in the study area under different rainfall recurrence periods,evaluate the drainage capacity and waterlogging risk of the system,simulate the improvement of waterlogging after the implementation of different treatment schemes,and evaluate the treatment effect.A resilience evaluation method of urban road waterlogging based on MIKE model was proposed.The resilience evaluation index system was constructed byconsidering the stability and recoverability of road affected by waterlogging,and the weight of each index is determined by analytic hierarchy process.[Results]Insufficient drainage capacity of the pipe network was the main factor leading to the risk of waterlogging in the central urban area.More than 55%of the pipe network drainage capacity was less than once a year and 76.11%of the pipelines were not up to standard under the 5-year rainfall condition.The high-risk area of water accumulationis concentrated at the intersection of Bayisi Road and Wulong Road.The maximum depth of water accumulation reachs 1.14 m under the condition of 30-year rainfall,the resilience index decreased to 0.28.Three pipeline reconstruction schemes were proposed to improve the drainage capacity.After comparison,Scheme 2,as the optimal scheme,can greatly improve the drainage capacity of the central urban area.The water accumulation points were basically eliminated,and the water accumulation area was reduced by 57.14%,the resilience index decreased to 0.64.[Conclusion]Based on the MIKE model,the waterlogging situation under different scenarios in the central urban area can be simulated.According to the simulation result,the main causes of waterlogging risk and the evaluation of road waterlogging resilience can be systematically analyzed which can provide technical support for the formulation of targeted drainage schemes and flood risk management in the central urban area.关键词
