ABSTRACT
This thesis intends to design a construction plan for Sichuan Dabashan S316A2 . It is the second class highway and it’s design hour volume is 60 Km/h,design life is 12 year.
In this instruction, it explains the design's thread, basis of references; the section's geology; the process of working out the target, and the process of counting. The instruction is consisted of two parts: the literal interpretation and calculation specification, which include: paper location, the design of flat alignment, profile alignment, associating flat and profile alignment, roadbed transect, culvert, abamurus, the structure of road surface; the drawing of construction budget file, the information of references and so on.
The plane linear design includes information compiling, lines drawing on paper, fix on requisites of curves; Vertical section design is comprised of road elevation, design elevation, depth of dig and fill and requisites for vertical curve; Contents of horizontal section design are fixing standard horizontal section, mapping every horizontal section; At last make a blueprint according to traffic information and road design rules. The whole process of the design is carried out according to the criterion of nation.
