摘要
为了巩固我们所学的知识，并在各方面得到更进一步的提高，我们选择了贵州某地区新建二级公路设计作为毕业设计，这是在毕业之前对自身学习状况的最后一次检查。
我所选择的设计路段是从K0+000至K2+212.567段，全长2212.567米，设计车速60km/h,路基宽度为10m。
此次毕业设计主要包括的内容如下：
1、路线设计：在已知平面图的情况下，进行纵断面的设计，要求线路顺畅、填挖
平衡、经济合理。
2、路基设计：包括各个桩号的填挖计算、填挖较大地段的稳定分析、整个线路的土
石调运借配等。
3、路面设计：路基在不同干湿状态下，所设计的沥青路面和水泥混凝土路面方案的
比选，要求经济合理，便于施工并满足各设计规范要求。
4、路基、路面排水工程；高填挖地段的防护工程以及路基加固工程：这一部分相当
重要，对于路基排水，采用了边沟、截水沟、急流槽等排水设施；对于路面排水，除了对路面进行了路拱设计，还进行中央分隔带的排水设计；对于特殊路段的防护和加固主要采用了骨架内植草和挡土墙。 5、桥涵设计：包括桥梁和涵洞的形式、尺寸的设计。 6、专题研究：对此行业新观点或者新技术的综述。

Abstract
In order to consolidate what we have learned knowledge, and further improve in all areas, we chose two highway design for the new Guizhou area as part of the graduation design, this is when the last check to own study condition before graduation.
I choose the design road section is from K0+000 to K2+212.567, the total length of 2212.567 meters, the design speed of 60km/h, subgrade width of 10m. This graduation design mainly includes the following contents:
1, Route design: given a planar graph case, design of the vertical section, request line smooth, cut and fill balance, reasonable economy.
2,.Subgrade design: including each pile excavation calculation, cut fill large sections of the stability analysis, the whole line of earth rock allocation by matching etc.. 3,Design: pavement subgrade under different dry and wet conditions, comparison and selection of the asphalt pavement and cement concrete pavement project requirements, reasonable economy, convenient construction and meet the design requirements.
4,The roadbed, pavement and drainage engineering; reinforcement of high fill and excavation section and subgrade protection project: this part is very important, for the drainage of subgrade, the side ditch, ditches, chute, drainage facilities; for road surface drainage, in addition to the pavement of road design, also the drain design of medial divider; protection for the special section and reinforcement mainly adopts the framework of grass and retaining wall.
5,Bridge design: design including the bridge and culvert form, size. 6,Research: review the industry new ideas or new technology.
