Main Content

During these two weeks, the work of my project has made much progress. The main work of
these weeks is to design the vertical section of the highway. There are two main lines in the
drawing of vertical section, the first one is ground line and the other one is design line.
As a highway of design speed is 80km per kilo, the biggest longitudinal slope is 5%.The
biggest longitudinal slope is a very important index in the highway project. A appropriate
longitudinal slope should satisfy all aspects of the highway design.
Design of the vertical section has six steps:
Firstly, leveling center stake and drawing the ground line.
Secondly, labeling the location of the control point.
Thirdly, trying to decide several lines and compare with each other.
Fourthly, after one appropriate line is decided, it should be adjusted.
Fifthly, checking and decide the best longitudinal slope.
After these two weeks ,I have great progress to design of vertical section. I am quite glad to
see that. Next two weeks ,I will work harder.
