文档介绍：黄松甸至敦化二级公路施工图设计
(K128+130—K130+200)
摘要
本次设计的吉林省黄松甸至敦化二级公路是顺应国家发展战略大纲领的步伐。设计中克服了两地地势起伏较大等不利因素,采用较高标准来确定曲线半径,直线长度等要素。本设计是在对交通进行分析,查找相应的技术规范的基础上,确定出公路的技术等级以及设计需要的各种参数,结合周围的地形情况进行了平面线形设计,平面线形中有三个转角。纵断面的设计中有两个竖曲线,满足平纵线形组合设计中的各种要求。在横断面的设计中,确定了横断面组成及各种要素后,绘制出横断面图。采用沥青混凝土路面,路面材料的各项指标均符合相关标准、规范的要求。此段公路建设的完成必将为促进两地文化交流,发展两地经济等带来划时代的意义。同时推进了国家公路网的建设。

The Secondary Roads Ronstruction Design
of Huang Song Dian to Dun Hua
(K128+130—K130+200)
Abstract
Jilin province Huang Songdian to dunhua secondary roads of this design is to keep up with the pace of the national development strategy programme. Design to e the unfavorable factors such as topography ups and downs is bigger, use higher standard to determine the curve radius, length of the straight line, etc. This design is the analysis of traffic, find the corresponding technical specification, on the basis of determine the road technology level and the various parameters of the design needs, combined with the surrounding terrain for the horizontal alignment design, three Angle in the horizontal alignment. Profile design, there are two vertical curve, and meet various requirements in the design of flat vertical bination. In the design of cross section, to determine the cross position and various elements, to map the cross-sectional view. Use of asphalt concrete pavement, pavement materials in all kinds of indexes accord with the requirement of relevant standards and norms. pletion of this section of the highway construction will certainly to promote cultural exchanges, both development in both economy brought epoch-making significance. At the same time to facilitate the construction of the national work.
