文档介绍：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,我选择了S314三门峡至荥阳一级公路DE段作为毕业设计,这是在毕业之前对自身学****状况的最后一次检查。
我所选择的设计路段是从K4+950至K7+300段,全长2350米,设计车速80km/h,。
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、英文翻译
7、专题研究:对此行业新观点或者新技术的综述。
关键词:路线,路基路面,桥涵,排水,综合设计
Abstract
In order to strengthen our knowledge that we have learned, and to receive further improve in all aspects, we choose a new level of highway, which is from Sanmenxia to Xingyang , as my road engineering graduation design, and this is the last examination for what we have learned before our graduation.
In this design, our task is to design an secondary road. The road, which is 2350 m from K4+950 to K7+300. Whose design speed is 80km/h and the wide of the subgrade is .
Our prime contents of the graduation design project includes as follows:
design of the route: Conduct the longitudinal design and make sure that the line smooth fill in the required big balance, reasonable economy, in condition on the landform which is known.
2. The design of the subgrade: The work involves a lot of items: analyze the stability of brae; the fill or dig height of every peg and so on.
3. The design of pavement: This design contents that the select of the construction about concrete and asphalt pavement in different case, and require the economic reasonable, facilitating construction and meet the design requirements specification.
design of the subgrade pavement and the drainage engineering, high embankmentarea dig protection engineering and roadbed reinforcement engineering, as for the subgrade drainage, the ditches, cut ditch, the rapids chamfer drainage, this part is quite important. As for the pavement drainage, apart from the arch design
