基于SWMM的高速公路服务区排水系统优化研究
|
摘要
高速公路服务区是为驾乘人员提供休息、加油和维修等服务的场所,对防洪排涝有较高的要求。为了快速分析和解决服务区地表积水问题,首先采用传统单排水系统SWMM模型对某服务区重现期为2,5,20 a的暴雨进行模拟,分析其地下管网排水状况;然后在传统模型基础上利用双排水系统理论完善模型,进而分析出其地表积水情况;最后针对服务区积水情况,采用低影响开发(LID)措施和管径修改对排水系统进行优化。模拟结果表明:对于重现期为5 a的暴雨,存在部分管道超载,无地表积水;对于重现期为20 a的暴雨,服务区多处地表积水,最大积水深度为30 cm;通过优化措施后,服务区可基本解决排水问题。研究结果可为服务区分析和解决积水问题提供技术参考。
Express highway service area is a place to provide rest, refuel, maintenance and repair services for the drivers, and has higher requirement for flood control and drainage. In order to quickly find out and solve the waterlogging problems in the service area, firstly, the traditional SWMM model of single drainage system was used to simulate the rainstorm in a service area with rainfall recurrence periods of 2, 5, 20 years, the underground pipe network drainage conditions were analyzed. Secondly, based on the traditional model, the dual-drainage system theory was used to improve the model, and the surface waterlogging conditions were analyzed. Finally, the drainage system was optimized by using low impact development(LID) measures and pipe diameter modification in view of waterlogging conditions. The simulation results show that there are some pipelines overloading and no waterlogging for a recurrence period of 5 years; for a recurrence period of 20 years, most area are waterlogged and the maximum waterlogging depth is 30 cm; after taking optimization measures, the drainage problem can be basically solved in the service area. The results can provide a technical reference for analyzing and solving waterlogging problems.
