【摘要】：世界各地的城市內(nèi)澇問(wèn)題日益突出。針對(duì)這一問(wèn)題，以南昌市青山湖片區(qū)為例，采用SWMM模型對(duì)其在實(shí)際暴雨條件下的雨洪過(guò)程進(jìn)行了研究分析。主要取得了以下結(jié)論： （1）對(duì)SWMM模型的原理和步驟進(jìn)行了總結(jié)和闡述，結(jié)合南昌市青山湖片區(qū)排水管網(wǎng)建模實(shí)例，采用劃分子匯水區(qū)域、設(shè)定模型參數(shù)、模型校準(zhǔn)的模型構(gòu)建方法，，初步建立了南昌市青山湖片區(qū)排水管網(wǎng)模型。 （2）運(yùn)用SWMM模型對(duì)研究區(qū)域模擬和城市室外排水法計(jì)算兩種方式，比較兩者得到的雨洪峰值，從流量方面探索到重現(xiàn)期銜接的關(guān)系。這對(duì)南昌地區(qū)城市排水標(biāo)準(zhǔn)與城市排澇標(biāo)準(zhǔn)的協(xié)調(diào)統(tǒng)一有著一定的借鑒和指導(dǎo)意義。 （3）基于SWMM模型建立的南昌市青山湖片區(qū)排水管網(wǎng)模型，評(píng)價(jià)了現(xiàn)有排水管網(wǎng)系統(tǒng)的排水能力，找出了典型暴雨下的積水點(diǎn)和超載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.
