山区某快速路排水工程方案研究

Study on Drainage Engineering Scheme of an Expressway in Mountain Area

以四川省自贡市高铁连接线为例,分析了山区快速路不同类型道路的排水系统设计。具体介绍了山区快速路排水方式的选择、下穿立交排水、地道排水、高架排水、过水涵洞排水等的特点,探讨了合适的排水设计标准和因地制宜的排水系统方案。

Taking Zigong High-speed Rail Connecting Line in Sichuan Province as an example,the drainage system designs for the different types of expressways in mountainous areas are analyzed.The selection of drainage mode of expressway in mountainous area,and the characteristics of underpass drainage,subway drainage,viaduct drainage and in-water culvert drainage are introduced in detail.The appropriate drainage design standard and the drainage system scheme according to local conditions are discussed.
