【摘要】：城市雨洪系统在城镇基础设施建设中具有重要作用，起到了排渍、排涝、防洪的作用。随着我国城市化进程不断加快、城市人口不断增加、城市规模不断扩大，相应的雨洪系统不断延伸，许多城市防洪排涝设施建设已经不能满足城市安全与环保等方面的要求，各地雨洪系统中出现各种灾害问题，给城市经济发展、人民生活和生产带来了极大影响，需要对城市雨洪系统进行合理的规划设计。在城市规划中，传统的防洪工程规划、雨水工程规划方法很难解决日益快速的城市化发展需求，需要寻求更加科学合理的规划设计方法以解决日益复杂的城市雨洪系统中存在的各种问题。随着计算机技术的快速发展，利用数学模型方法解决雨洪系统规划中的各种问题越来越受到各方的关注。综述了雨洪排除系统模型的基本理论，介绍了雨水排除系统数学模型机构成与模型的应用情况。通过与国际上现有的各种雨洪排除系统模型分析比较，分析了SWMM模型对用于雨洪系统规划的适用性。论述了基于SWMM模型模拟的理论方法与步骤，重点论述了子流域概化、各种计算子模型以及建模的基本步骤，并对SWMM模型中的各参数进行了律定。以西北某典型城市为研究区域，考虑该城市现状及未来的发展、用地性质、地形特点、天然界限（河流）以及下垫面形式等差异，将该城市概化划分六个汇水区域，建立SWMM计算模型，，并对不同汇水区域的雨量进行模拟分析，模拟结果能明确指示各汇水区域雨洪排放工程中存在的问题，分析各子汇水区域哪些排水管道的排水能力，特别是在大暴雨情形下可能产生的雨洪灾害问题节点，研究结果可为该城市雨洪工程改造提供可靠的优化方案。
[Abstract]:City rainwater system plays an important role in urban infrastructure construction, the drainage, drainage, flood control role. Along with our country city to speed up the process, the city population continues to increase, the city continues to expand the scale of rainwater system corresponding continuous extension, many city flood control and drainage facilities have been unable to meet the city safety and environmental requirements, various disasters occur around the stormwater system, to the city economic development has brought great impact on people's lives and production, the need for city rainwater system design. Reasonable planning in city planning, flood control planning of traditional planning method, it is difficult to solve the city rainwater project the development of fast growing demand, need to seek a more scientific and reasonable planning and design methods to solve various problems of city rainwater system is becoming more complicated. With the development of computer technology in The rapid development of the mathematical model method to solve various problems in the planning of rain and flood system has attracted more and more attention.
The paper summarizes the basic theory of rainwater exclusion system model, introduces the application of rainwater drainage system mathematical model and mechanism model. Through the analysis of the international and the various existing stormwater removal system model comparison, analysis of the SWMM model for applicability of rainwater system planning. Discusses the theoretical methods and steps of SWMM model based on the focus on the sub basin is summarized, the basic steps of various calculation model and modeling, and the parameters of SWMM model in the law.
In a typical city in Northwest China as the study area, considering the current situation and future development of the city, the nature of land use, topography, natural boundaries (rivers) and surface form difference, the city is divided into six generalized catchment area, the establishment of SWMM model, and the different catchment rainfall simulation analysis the simulation results indicate, the catchment area of rainfall flood drainage project in question clearly, analysis the drainage capacity of each sub catchment area which drains, especially node stormwater disaster problems that may arise in the case of heavy rain, the research results can provide reliable optimization scheme for the transformation of the city rainwater project.
