【正文】 way. Then, according to this grade to choose two routes in given terrain map. Up to date, the design is started really. The content includes the plane design, the vertical section design, the transect design and the choosing of position for bridges and culverts. The last step is choosing the better project and the choice should been made between the two routes which have been selected. In the part of detailed design, the first step is picking out one point four kilometers routes from the preliminary design. Concretely, the plane design is same as the preliminary one, the vertical section design has been adjusted before the volume of earth and rock. After this, subgrade, pavement and drainage (especially culverts) have been designed in stress. At the last step, we should pile the project budget. This design is primary about calculating architectural and installing cost.
