青岛理工大学 毕 业 设 计（论 文） 题目：潍坊至临沂一级公路设计 摘 要 本设计为潍坊至临沂一级公路设计，按山岭重丘区一级公路技术标准设计，山岭地区地形复杂多变，因此在选线时应充分利用有利地形，合理避让不利地形，从而使线形满足相应的设计要求，并达到安全、舒适、美观的效果。 本设计主要分为四部分，分别为：平面设计，纵断面设计，横断面设计，路面结构设计。 本公路设计速度为80km/h，路线全长4194.155米，按双向四车道设计，设中央分隔带，路基宽度24.5米，平面有一个弯道，弯道的最小半径为270米，直线最大长度1515.377米。路线平均纵坡1.249%，最大纵坡2.004%，最小纵坡0.251%，纵断面有3个变坡点，最小竖曲线半径为111.986米，共设置了6处涵洞。 关键词 平面设计，纵断面设计，横断面设计，路基设计，路面设计 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, complex 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, comfortable, beautiful results. This design is mainly divided into four parts, there are as follows: graphic design, profile design, cross-section design and pavement structure design. The highway design speed is 80 kilometers per hour, the route length of 4194.155meters, designing as four-lane highway with two-way streets, a central median and the width of the roadbed is 24.5 meters, This plane has one bend, the minimum bend radius is270meters, and 1515.377 meters maximum length of line. Average longitudinal line of this section is 1.249 percent, and the largest longitudinal is 2.004percent, 0.251percent minimum longitudinal slope. Four change points in vertical alignment, the minimum vertical curve radius is111.986 meters. Were set up six culverts. The road of asphalt concrete pavement, according to standard recommend 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.
