1、摘 要 I 摘摘 要要 本次毕业设计为佳木斯至牡丹江三级公路（A）标段，所经地区全境地势重丘， 自东北向西南略呈倾斜。中部为山岭区。主要进行公路线形、路基和路面设计。其 中，线形设计包括选线、方案比选、平面设计和纵断面设计；路基设计包括横断面设 计、路基边坡设计等；路面设计包括路面结构层设计、路面结构层厚度设计和路面结 构层验算。通过对当地交通量、地形、气候、水文、地质等状况的深入调查, 确定了 道路的等级以及道路设计的各个技术指标，为公路路线方案的比选准备了原始材料， 确定了线路的平面位置。并且本设计对方案进一步细化，对路线的平面和纵断面进行 了综合分析，根据技术标准及当地实际情况确定了路基

2、宽度、高度及边坡坡度并且对 路面材料、横断面布置、曲线超高及加宽的设置做了精心设计。 关键词关键词: 线形；缓和曲线；竖曲线；路基；路面 II Abstract This graduation design is the (R) segment of the second class road which starts from Xinxiang to Tongling.This second class road goes through mountain region.and mainly carrys on the road alignment, roadbed and pavement

3、 design. Then,alignment design includes to choose the line, project to compare to choose, the flat surface design and vertical section design.The roadbed design includes the cross section design and the roadbed side slope design etc; The pavement design includes pavement structure layer design, pave

4、nent structure layer thickness design and pavement structure layer to check to calculate. According to investigating the further state of the volume of traffic, local topography,climate,hydrology,geology,etc,then confirms the class of highway and technical standard,selecting to prepare the firsthand material of scheme of the highway, and fixing the level of the circuit. Furtherly i design the details and have analysis of the circuit and vertical section.Accord to the technical standard and l
