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，我们选择了重庆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+274.5段，全长2274.5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。
桥涵设计：包括桥梁和涵洞的形式、尺寸的设计。
