摘 要
本设计为高速公路设计，设计部分的公路全长3589m，设计车速100km/h，双向四车道，设置中央分隔带。共设有2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240米，圆曲线半径800米。第二个弯道也设有缓和曲线，长度为280米，圆曲线半径800米。根据规范，圆曲线只设超高不设加宽。整个路段共设有四个竖曲线，竖曲线半径均设为18000米，并且满足了平纵面线形组合设计中的要求。路拱采用双向坡面，坡度值采用2%。在横断面的设计中，确定了横断面组成及各种要素后，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。在挡土墙设计中满足了各种稳定性的验算。路面设计内容中包括路面类型与结构设计，路段路面设定两种方案，分别为沥青路面以及水泥混凝土路面。关键词：高速公路 山岭重丘 沥青路面 水泥混凝土路面
Abstract
This is designed to high-speed highway design，Design part of the total length of highways 3589 m, the design speed 100 km / h，four-lane two-way，set Medium Divider. There are two-curve，in all round There will be a relaxation of the curve. The first corner with ease curve，easing curve length of 240 meters, round curve radius of 800 meters. The second corner is also a transition curve，a length of 280 meters，round curve radius of 800 meters. According to norms, with a round of a super-high not only for widening. There are entire sections of four vertical curve. There will be a radius of vertical curve for the 18,000 meters，and meet the vertical surface-linear combination of design requirements. Slope used two-way road humps，a gradient of 2 percent. In cross-section of the design，composition and determine the various elements of cross-sectional，drawing cross-sections. Roadbed design elements that determine the shape and slope roadbed slope. In the design of retaining walls to meet a variety of stability of checking. Design elements include road surface types and structural design，set up two sections of the road programme，namely the asphalt pavement and cement concrete pavement.Key words: Highway Mountain-Hill Asphalt Pavement Concrete Pavement
