1、 - - I 摘要摘要 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，我们选择了苏州至无 锡某新建一级公路工程设计作为毕业设计，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 K3+651.654 段，全长 3651.654 米，设计车速 80km/h,路基宽度为 24.5m。 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、路基、路面排水工程；高填挖地段的防护工程以及路基

2、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；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。 4、路面设计：路基在不同干湿状态下，设计沥青路面要求经济合理，便于施工并 满足各设计规范要求。 关键词关键词 路线；路基路面；综合设计 - - II Abstract In order to consolidate our knowledge, and in all respects to be further improved, we chose LiaoNing province a new highway d

3、esign as part of the graduation design, it is before graduation of their learning situation for a final check. In this design, our task is to design an secondary road. The road, which is 3651.654 m from K0+000 to K3+651.654. The design speed is 80km/h and the wide of the subgrade is 24.5m. 1、Route d
