1、1 设计题目：彭泽二级公路 K6+000K7+880.761 段施工图设计 摘摘 要要 在本设计中，主要是进行彭泽二级公路的设计。设计部分的公路全长 1880.761m，设计车速 80km/h，双向二车道，不设置中央分隔带。 本设计公路等级为二级公路，首先在平面图中进行选线，然后对公路路线 进行了平面线形设计。 在本设计公路平面线型里设置一段直-缓-圆-缓-直的基本 平面线形，并设置超高。纵断面的设计中有两个竖曲线，且基本上满足了平纵线 形组合的各种要求。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。然后进行 超高计算和土石
2、方的调配以及路面设计。 确定平曲线以及纵曲线之后之后即可进 行涵洞以及桥梁的设计，本设计采用多个圆管涵和 1*10m 的简支板桥！ 通过本次毕业设计，不但了解了公路桥涵建设的各个步骤，而且也能熟练 的运用 AUTOCAD 与桥梁博士等专业软件！ 关键词关键词 二级公路 线形设计路面 路基 涵洞 简支板桥 Abstract In this design， is mainly the pengze expressway design， the length of this road which we design is 1880.761m， the design of the speed is 8
