1、摘要我国交通事业迅速发展,新建公路工程层出不穷。同时,很多早期规划的路段都不能满足需要,公路改建势在必行。老路的改建必将越来越多,因此,改建技术急需进一步研究与提高,以完善国家基础设施建设,满足日益增长的交通需求。本文以S336江都段改造工程施工设计为研究对象。S336江都段改造工程路线全长13.714km,全线采用具有集散功能的平原微丘区一级公路标准,设计计算行车速度80km/h,集镇段限速40km/h。本设计范围为通江段(K5+888.224~K13+714.437)。该段路基采用整体式24.5
2、m标准一级公路断面。路线共跨越四条河流,与平面交叉共三处,与乡村道路交叉共6处。本文在工程可行性研究的基础上,完成了路线、路基、路面的设计。介绍了工程的设计背景及沿线的水文地质等概况,并对工程的设计概况进行总体说明。结合施工图设计的整个过程,较全面地阐述了平原地区高等级公路改造工程的路线、路基、路面的设计原则和方法,着重研究了路线方案的比选、特殊路基的设计以及路面结构的设计。关键词:路线路基路面施工图设计AbstractToday,ourcountryroadtrafficcausedevelops
