【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。
[Abstract]:The problem of urban waterlogging around the world is becoming increasingly prominent. To solve this problem, taking Qingshan Lake area of Nanchang City as an example, the SWMM model is used to study and analyze the rain flood process under the actual rainstorm conditions. The main conclusions are as follows: 1) summarizing and expounding the principle and procedure of SWMM model, combining with the example of drainage pipe network modeling in Qingshan Lake area of Nanchang City, adopting the method of constructing model by dividing sub-catchment area, setting model parameters and calibrating model. The drainage pipe network model of Qingshan Lake area in Nanchang City was preliminarily established. 2) using the SWMM model to simulate the study area and calculate the urban outdoor drainage method, compare the rain Hong Feng values obtained by the two methods, and explore the relationship between the flow rate and the recurrence period. This has certain reference and guiding significance to the coordination and unification of urban drainage standard and urban drainage standard in Nanchang area. Based on the SWMM model, the drainage pipe network model of Qingshanhu area in Nanchang city is established. The drainage capacity of the existing drainage network system is evaluated, the water accumulation point and the overloaded pipe section under typical rainstorm are found out and the improvement measures are put forward.
