1、洛阳理工学院毕业设计(论文)敦化市大梨树村至富河村二级公路施工图设计摘要本毕业设计是进行二级公路设计。本设计段的路线长1914.592米,设计车速80km/h,双向两车道。对交通量进行了分析,查找相应技术规范,确定公路的等级及设计需要的各种参数。在平面图中进行选线,然后对道路路线进行平面线形设计。纵断面设计中有1个竖曲线,并且也满足了平纵面线形设计中的各种要求。在横断面的设计中,确定了横断面的组成及各种要素后,绘制横断面图。路基设计的基本内容就是确定路基边坡的形状和坡度。路面设计内容中包括路面类型与结构设计。通过这次设计,不但了解了设计公路
2、的各个步骤,而且也能熟练运用AutoCAD等制图工具进行作图。关键词:二级公路,线形设计,路基设计,交通量TheSecondaryRoadsConstructionDesignHightideagainstCCPbloodyanTomb,CommunistPartymembersandpartoftheexposedTombareavacatedbyprogressiveyouth.IvisitedinBeijingin1985whenitwasoldundergroundcomrade,sisterofYaoZhiyingYaoMuzhe
