毕业设计某高速公路分段第二段路基路面综合设计 完整版.rar

摘 要
本设计主要介绍了某高速公路路线的设计过程。根据给定的资料，通过对原始数据的分析,以及该路段的地质、地形、地物、水文等自然条件,依据《公路工程技术标准》 《公路路线设计规范》等交通部颁发的相关技术指标,在老师的指导和同学的帮助下完成的。
该路段所经地区是平原微丘区，公路设计速度为100km/h，为双向四车道高速公路，路线全长1396.29米，路基宽度为26米，共设有1个平曲线，1个竖曲线。路线设计内容包括平面设计、纵断面设计和横断面设计；其后进行了路面排水设计，采用边沟、排水沟和截水沟进行排水，保证路基路面的水稳定性；最后进行了路面结构的组合设计等内容。
整个设计计算了路线的平、纵、横要素,设计了路基、路面等内容,由此圆满完成了某高速公路的设计。

Abstract
This paper mainly introduces the design process of the highway. Based on the information given by the analysis of the raw data, and the section of geology, topography, terrain, hydrology and other natural conditions, according to "Highway Engineering Technical Standard", "Road Design Standards" issued by the Ministry of Communications and other related technologies indicators, I have finished this task under the teacher's guidance and help from students.
The area that this highway passes through belongs to plain with micro-hill area.This highway of design speed is 100km/h with bi-directional four-lane first-grade highway, with route length of 1396.29 meters, embankment width of 26 m, one horizontal curves, and one vertical curves. Line design including graphic design, longitudinal design and cross-sectional design; Then I accomplished the pavement drainage design, which uses ditches, drains and drainage ditches for drainage to ensure the water stability of roadbed and pavement; at last, a composite design of pavement structure and other designs are also finished.
The whole design have calculated the planar, vertical and horizontal elements of this line, besides roadbed, pavement and so on, thereby making it possible to successfully complete the preliminary design of the highway.


Key words: Graphic design ; Longitudinal design ; Cross-sectional design; Drainage design; Pavement structural design
