1、湖南工业大学科技学院毕业设计(论文)摘要某二级公路公路建设对沿途地区的经济发展起着很大的作用。本路线途经山岭重丘区,本着安全、经济、实用、美观的原则,对该路段进行施工图设计。某二级公路施工图设计是在所在地区的地形、地质、气候的影响下,按照设计规范进行的。本次设计的内容有:平面线设计、纵断面设计、横断面设计。平面线设计包括纸上选线、定线,圆曲线、缓和曲线参数设定,直线设计等;纵断面设计包括拉坡、竖曲线设计等,超高的设定一满足了设计要求的8%之内,在竖曲线设计时,应注意行车视距和视线诱导问题即满足“平包纵”,合成坡度
2、也要满足规范要求;横断面设计时,使行车更加舒适,为确保道路的使用年限,在路段上还做了防护和排水设计。排水设计包括路基排水和路面排水,路面设计又有边沟设计和截水沟设计和路拱排水。施工图是工程的重要组成部分,可以使道路的实用性和经济性得到更好的保证,同时,也要求道路的美观性和实用性、经济性相结合。关键词:施工图;路基设计;平面;横断面;纵断面;89湖南工业大学科技学院毕业设计(论文)AbstractWorkingproperlytohopesecondclasshighwayisthenationalhighwayg
