Subgrade design width of 34.5 m, six lanes and closed the entire free way. According to a variety of information and the basis for the design, We
3、finish the road design (graphic design, profile design, cross-sectional design, level design and vertical composition and deployment of calculation of earth and stone) by the natural conditions, technical standards and design technology and major economic indicators. Then the subgrade for the design
4、: cross-sectional layout embankment and subgrade drainage, protection and subgrade for the special design. Then on the pavement to the design: a road traffic axle load conversion after the design of the pavement structure, and the stress checking. Finally, the design of retaining walls, bridges, culverts and environmental protection and a simple landscape design. Key words: Wuning - Jian free way, the alignment design, the subgrade design, pavement design. iii 目目 录录 1 设计资料与依据设计资料与依据1 1
