Abstract
In this design, is mainly the dongshen expressway design, the length of this road which we design is 3500m
, the design of the speed is 100km/h and set up the central of separation strip.
Has carried on the analysis to the volume of traffic, search corresponding technical specifications,
highway to determine the levels of need and the design of the parameters . Carries on the route selection in the
horizontal plan, then carried on the plane geometric design to the path route. This route has two sections of
curves establishments transition curve and super elevation. There are five vertical curves in this Profile Design.
And also meet various requirements of vertical surface linear combination design.Has determined the cross section
composition and various elements in Cross section design and draws up the cross section chart. The roadbed design of
basic content is determining roadbed side slope form and slope. In the design of retaining walls is to meet a
variety of recalculations Stability. Pavement Design elements include road type and structure design. Final
budgetary is estimate design for computer assistance computation, also discussed some of the content of the forms
and drawings.
This design not only to understand the various road-building steps, but also skilled in the use of AutoCAD
