基于六边形格网的城市内涝洪水演进方法研究
|
摘要
基于六边形格网建模的方式研究城市内涝洪水的演进过程,采用离散格网的方法,建立了一种基于规则多尺度离散格网的城市几何模型,通过三维地形测量数据和二维建筑物矢量数据的融合,形成了规则的地表格网模型,该模型同时考虑了城市地形和建筑等特殊阻拦体。在此基础上,提出了一种逆向的水流推演方法,由洪水的状态反算演进过程,即以洪水的水淹深度为基础,通过与出(排)水口的连通性,计算水淹的范围,由此实现了城市内涝洪水的模拟推演。试验表明,本文方法能够有效地实现城市内涝场景的演进推演,可以为城市防减灾与应急决策提供科学依据。
An evolution of the urban waterlogging flood routing was studied in this paper based on the method of hexagonal grid modeling.Using the method of discrete grid,established an urban geometry model on account of the regular multi-scale discrete grid.With the fusion of 3Dtopographic survey data and 2Dbuilding vector data,formed a regular network model of surface.This model took multi special block into account,such as urban terrain and buildings.On this basis,a method of reverse flow deduction was proposed,which was an inverse computation from the state of flood to the evolution process.That is,based on the water depth of flood,made use of the connectivity with the outfall to calculate the range of water logging,and then implemented the urban waterlogging flood simulation deduction.The test indicated that,this method can implement the evolution of urban waterlogging scenario deduction effectively.And the correlational research could provide scientific basis for urban disaster prevention and emergency decision-making.
