How to construct a skew bridge?
A skew bridge refers that a bridge longitudinal direction axis is not vertical to crossed river flow direction or route axis. The skew bridge is often seen in intersections of two highways or more.
How to construct a curved bridge?
Usually we construct a bridge, the max cross slope may be 5%. In the condition, what can we do?
Firstly if there is a cross slope, it will be a curved bridge. According to the theory of centrifugal force, the bridge shall be lower inside than outside so that traveling vehicles are not thrown out.
How to construct upslope bridges and downslope bridges for a launching gantry?
As the launching gantry construct the bridge, we usually meet a lot of different working conditions like longitudinal slope. In this case, we have to adjust height of support legs to create a suitable construction environment.
I will take an example that how to construct a bridge with max longitudinal slope 5% which usually is the max gradient the launching gantry could be used.
