Abstract
According to the technical standards and specifications for highway design published by the Ministry munications of China, prehensive design of highway subgrade and pavement from K0+000 to K4+ been carried out based on the data of Changtu-Diaobingshan secondary roads in Liaoning Province. The designed vehicle speed is 80km/h , bidirectional two traffic lanes.
The main contents of the design included highway line of graphic design, vertical alignment design, line cross-sectional design, subgrade and pavement drainage, pavement structure design, the design of small bridges, construction design, and the preparation of budget estimate, ect. In the plane design, considered is the mountainous terrain area newly built road, I have chosen four points of intersection on the Lines in the design roads, the point of intersection radius respectively is 500m, 600m, 300m, 370m,. In the profile section design, the entire line has six to change the slope spot, the radius respectively is 12500m, 10000m, 3800m, 112100m, 10000m,3400m. The small arch of bridge design has mainly carried on the bridge putation and putations. Design is a 18 meters of reinforced concrete T-beam bridge. In addition, it has the related content of the anization plan and budgets and so on .
During this graduation design, the expertise is prehensive training, and the ability of independent analysis and solving problems were improved and strengthened, so good effects have been achieved.
Key words : Secondary roads;subgrade;prehensive design
