Methods of Bridge Construction
Different Methods of Bridge Construction Described below are the different methods employed in the construction of bridges. 1. Cast-in-situ Method of Bridge Construction This method is a flexible method of bridge construction where complex and unusual geometrical shapes of dams can be constructed easily. Situations when it is hard to transport pre-fabricated elements either due to size or unreachability, this method is a good choice. 2. Balanced Cantilever Method of Bridge Construction This method is used for constructing bridges with span 50 to 250m. The bridge constructed can either be cast-in-place or precast. Here, the segments are attached in an alternative manner at opposite ends of the cantilevers supported by piers 3. Precast Method of Bridge Construction In this method, the bridge is constructed with the help of precast concrete elements. Precast Beams Precast Decks Precast Segmental Decks 4. Span by Span Casting method of Bridge Construction This method is associated wi...
