| Abstract: | For the construction of long-span steel truss arch, side span steel truss needs to provide extremely large overturning moment during the erection of steel truss girders. So a new construction method is introduced, in which side span steel truss arch is supported by temporary piers; cross is installed using slings, and the entire bridge is closed at the middle of the span at last. |
