1、 - - I 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
2、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；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 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
3、a new highway design 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 2
