The main task of the design is primarily of routes, and to take into account the other aspects. The line design is determined according to the Highway grading standards to have the main technical and graphic design for the road on the route paring with the local. Considering filling dug balance and minimum height of filling, the profile design is drawn. M ake a design for the cross-sectional, then draw cross-sectional map. After have calculation of roadbed for widening and elevation, drafting the questionnaire design, earthwork calculations and deployment; To ensure road embankment in the stability of dry, it make road drainage facilities design; Elevation culvert size of the initial formulation, and have embankment works at the project budget. Keywords : Route Pavement Subgrade Protection Budget breakdown 内蒙古科技大学毕业设计说明书 3 摘要......................................................................................................................................... 1 Abstract ................................................................................................................................... 2 第 1章概述......................................................................................................................... 7 任务根据................................................................................................................. 7 项目建设的意义..................................................................................................... 7 涉及范围及主要工作内容..................................................................
