基于SWMM对南昌市青山湖片区排水管网模拟研究-市政工程专业论文.docxVIP

摘 要 世界各地的城市内涝问题日益突出。针对这一问题，以南昌市青山湖片区 为例，采用 SWMM 模型对其在实际暴雨条件下的雨洪过程进行了研究分析。主 要取得了以下结论： （1）对 SWMM 模型的原理和步骤进行了总结和阐述，结合南昌市青山湖 片区排水管网建模实例，采用划分子汇水区域、设定模型参数、模型校准的模 型构建方法，初步建立了南昌市青山湖片区排水管网模型。 （2）运用 SWMM 模型对研究区域模拟和城市室外排水法计算两种方式， 比较两者得到的雨洪峰值，从流量方面探索到重现期衔接的关系。这对南昌地 区城市排水标准与城市排涝标准的协调统一有着一定的借鉴和指导意义。 （3）基于 SWMM 模型建立的南昌市青山湖片区排水管网模型，评价了现 有排水管网系统的排水能力，找出了典型暴雨下的积水点和超载管段并提出了 改善措施。 关键词： SWMM；雨洪模型；排水管网；城市排水 I Abstract The problem of urban waterlogging is getting more and more attention-attractable all over the world nowadays. This dissertation works on doing researches of the stormwater process under the circumstance of real rainstorm; the SWMM model is used to analyzing the selected example of Qingshanhu District. Findings are listed below: This dissertation firstly introduces the understanding of SWMM model and preliminarily establishes the urban sewer system model of Qingshanhu District; the methods of sub-catchment delineation, model parameters selection and model calibration process are used in the process of establishing system model. This dissertation firstly introduces the understanding of SWMM model and preliminarily establishes the urban sewer system model of Qingshanhu District; the methods of sub-catchment delineation, model parameters selection and model calibration process are used in the process of establishing system model. The urban sewer system model of Qingshanhu District evaluates the flood-carrying capacity of current water discharging pipeline system and finds out the flooded streets and overloaded pipelines when typical rainstorm comes. Moreover, useful solutions are suggested to solve the problems in the dissertation.
