安徽理工大学土木工程毕业设计陕南地区C3标段道路设计摘要本设计选取路段为陕西省陕南地区C3标段K0+000-K1+522段，全长1.522公里，该路段属于山岭重丘区。全线采用双向四车道一级公路标准，设计速度60km/h，路基宽度23m，平曲线超高设置为8%，桥梁设计荷载为公路-I级，桥路同宽。路面设计为沥青混凝土柔性路面，本着安全、经济、实用、美观的原则，对该路段进行施工图设计。该段公路施工图设计是在所在地区的地形、地质、气候的影响下，按照设计规范进行的。本设计主要设计内容包括：平面设计、道路纵断面设计、道路横断面设计、路基设计、排水设计、路面结构设计及挡土墙设计。由于地形原因，设计中包含有桥梁工程和隧道工程。关键词：平面线形设计，路基设计，排水设计，路面结构设计，挡土墙设计，桥梁隧道设计THE ROAD DESIGN OF SOUTHERN SHAANXI C3 BID SECTIONABSTRACTThe selected section of this design is the C3 bid section for K0+000-K1+522 in Southern Shaanxi, a total length of 1.522 kilometers，the road belongs to the mountainous areas. Total line using two-way, four-lane highway standard, design speed 60km/h, roadbed width 23m, plane curve exceeding height is set to 8%, the design load of bridge is the road-I level, the width of bridge is the same as the road. Pavement design is asphalt concrete pavement, in a safe, economic, practical, aesthetic principles, start the construction design of this section.This design is located in an area where the topography, geology, climate, according to design specification. The main design elements of this design include: graphic design, road longitudinal section design, cross section of road design, roadbed design, drainage design, pavement structure design and protection design.Due to topography, the design included a bridge engineering and tunnel engineering.KEYWORDS: plane alignment design, roadbed design, drainage
