| Abstract: | With the construction of the Chuhe Main Canal Bridge of the Hefei-Liuan Expressway as a practical example, the main construction methods and processes, and control techniques for the construction of the first-simply-supported-and-then-continuous box girder bridge, such as techniques used for the pre-casting and erecting of box girders, and the conversion of different structural systems of the bridge, are introduced in detail in the paper. Practice shows that the fabricated, first-simply-supported-and-then-c... |
