摘要
成绵扩容高速公路为设计速度120 km/h、八车道高速公路,路面宽度宽、设计速度高,若路基、路面排水设计不合理,易出现雨天积水严重,导致行车不安全、路基出现水毁。通过将路基排水和路面排水有机结合,将其作为一个排水体系进行综合设计研究,满足路基、路面快速、顺畅排水需求,以保证工程和行车安全。
The design speed of Chengdu-Mianyang Expansion Expressway is 120 km/h,eight lane expressway,the width of road surface is wide,the design speed is high,if the drainage design of roadbed and road surface is not reasonable,it is easy to have serious water accumulation in rainy days,causing traffic accidents,roadbed water damage.Through the organic combination of roadbed drainage and pavement drainage,it will be integrated as a drainage system for comprehensive design and research,to meet the roadbed,pavement rapid and smooth drainage needs,to ensure engineering and traffic safety.
