1、1 I摘 要 设计为我国皖南山区的白莲岩公路设计，白莲岩地区隶属安徽省六安市，此地区地形属于山岭重丘。路段全长 2802m，拟为山岭重丘区的二级公路，共设有 3 个平曲线，在所有圆曲线处均设缓和曲线。第一个弯道设有缓和曲线，缓和曲线长度 60 米，圆曲线半径500 米。第二个弯道也设有缓和曲线，长度为 80 米，圆曲线半径 450 米。第三个弯道半径为 150 米，设缓和曲线，长度为 50 米。根据规范，第一和第二个圆曲线只设超高，第三个曲线设有超高和加宽。整个路段共设有一个竖曲线，坡度分别为 0.77%和 3.34%，半径设为 5000 米。路拱采用双向坡面，坡度值采用 2%。路段路面设定两
2、种方案，分别为沥青路面以及水泥混凝土路面。 关键字：一 级公路 平原地区 沥青路面 水泥混凝土路面 II ABSTRACT My design is the design for highway of BAILIANYAN of the south mountain area of Anhui in our country, BAILIANYAN area is in liuan city, Anhui Province , this regional topography is the hills. The total length of the highway is 2802m , it
3、was designed by the 3rd road in hill area, there are 3 curves altogether, have ease curves in all curve places . The first curved way relaxes the ease curve, the length is 60 meters, the radius of curve is 500 meters. The second curved way relaxes the ease curve too, the length is 80 meters, the rad
4、ius of curve is 450 meters. Third curved dishes of radius 150, is it ease curve to set up, length 50. According to the norm, the first and second curve only has the hyperlenth, the third curve has hyperlenth and widens. There is a vertical curve altogether in the whole highway section , the slope is
5、 0.77% and 3.34% respectively, the radius is set as 5000 meters. The way is joined and adopted two-wayly and domatically, slope value adopts 2%. The highway section road surface establishes two kinds of schemes, one is the asphalt road surface and another is cement concrete road surface. Key word: the 2rd highway； hills； asphalt surface； concrete surface
