摘 要

本公路是从上陵至埔前的一条高速公路，它的建设对完善路网，促进沿线地区经济发展，带动贫困地区早日脱贫致富，促进此地区的的交通发展，意义重大。本设计根据沿线地质、地形、水文等自然条件,依据交通部颁发的有关技术标准、规范，完成K0 000～K4 880段施工图设计。

本次设计应用纬地道路辅助设计软件HintCAD5.8、绘图软件AutoCAD2008、办公软件Offices2003等计算机工具，对公路路线、路基路面、排水工程、附属工程、平面交叉及沿线设施等进行施工图设计，并绘制出相应表格和图纸。本次设计对路面结构进行了一次对比设计，将沥青混凝土路面结构与水泥混凝土路面结构进行对比验算并且通过两者的比对得到沥青混凝土路面结构更加适合本次设计，最终确定沥青混凝土路面结构为4cm细粒沥青；5cm中粒沥青；6cm中粒式沥青；32cm水稳碎石；18cm石灰土。水泥混凝土路面构层厚度与沥青混凝土路面构层厚度设计，本着优质、高效、经济、合理的原则进行整体施工组织设计。

【Abstract】

This road is from the Shang Ling to the Pu Qian of a highway, the construction of to improve the road network, and promote the economic development of the area along the, promote early poverty in poor areas, and promote the development of traffic in the region, is of great significance. According to the natural conditions of geological, terrain, hydrology and other natural conditions, the design of the relevant technical standards and standards issued by the Ministry of communications is completed, and the design of the construction drawing of the K0 000 ~ K4 880 section is completed.

Computer tools for the design and application of weft auxiliary road design software HintCAD5.8, AutoCAD2008 graphics software, office software Offices2003 etc., on highway route, subgrade and pavement, drainage works, ancillary works, intersection and along the facilities of construction drawing design, and drawing the corresponding tables and drawings. The design of pavement structure were a contrast design, asphalt concrete pavement and cement concrete pavement structure of the comparison calculation and by comparing the two get the asphalt concrete pavement structure is more suitable for the design, and ultimately determine the asphalt concrete pavement structure is 4cm fine pitch; 5cm medium grained asphalt; 6cm in grain type asphalt; 32cm cement stabilized macadam; 18cm lime soil. The thickness of cement concrete pavement and the thickness of asphalt concrete pavement structure design, and the overall construction organization design based on the principle of quality, efficiency, economy and reasonable.
