【正文】 設(shè)計(jì)使用了緯地、 AutoCAD 等軟件來(lái)進(jìn)行設(shè)計(jì),這對(duì)我們今后步入社會(huì)工作很有好處?,F(xiàn)在公路運(yùn)輸發(fā)展速度迅猛,我國(guó)的公路里程已經(jīng)躍居世界前列。 關(guān)鍵詞 平面設(shè)計(jì),縱斷面設(shè)計(jì) ,橫斷面設(shè)計(jì),路基設(shè)計(jì),路面設(shè)計(jì) 青島理工大學(xué)畢業(yè)設(shè)計(jì) (論文) II ABSTRACT The design for the WeiLinDaDaoA4 ~ C1 level of highway asphalt pavement design, according to expressway’s technical standard of heavy hilly terrain in mountain areas, plex mountainous terrain, so the line selection should take full advantage of the favorable terrain, reasonably avoid adverse terrain, thus the linear design meets the appropriate requirements and achieve safe, fortable, beautiful results. This design is mainly divided into four parts, there are as follows: graphic design, profile design, crosssection design and pavement structure design. The highway design speed is 80 kilometers per hour, the route length of , designing as fourlane highway with twoway streets, a central median and the width of the roadbed is meters, This plane has one bend, the minimum bend radius is270meters, and meters maximum length of line. Average longitudinal line of this section is percent, and the largest longitudinal is , minimum longitudinal slope. Four change points in vertical alignment, the minimum vertical curve radius meters. Were set up six culverts. The road of asphalt concrete pavement, according to standard remend structure level 15 cm set asphalt concrete type do facing, 20 cm cement stabilized macadam and 35 cm lime soil do the grassroots, total ply pad to 70 cm.
