Abstract
[Abstract]：The design of the task is to guangxi qinzhou chung road. 5 left level of K12 +.000 ~ K14 + 516.257 section, mainly through the area for the high mountains, 2516.257 micro area, design for 80km per m/h j, cheiloschisis or palatoschisis meters wide road embankment 25.50 meters wide bandwidth, including the middle road both hard and 3.0 meters wide shoulder shoulder wide road and 3.0 meters 0.75 meters. Using cement concrete surface, grass-roots for cement-stabilized granular, cushion for 18cm gradation crushed stone materials (gravel). The main design includes: sure, the choice of highway grade route, linear curve elements calculation, paint line longitudinal diagram, vertical curve, typical drawing route computation elements, dredging, transverse route computation, design of high road pavement structure, protection engineering design, engineering, design of roadbed drainage budget and the construction organization design, the design of six, including culverts, dark circle culvert board GuanHan 5.
