| Abstrait: |
The Moolchand bridge is located on the Delhi metro line 3 extension. It crosses a highway and a roadway with a high traffic. No intermediate pier could be placed on the highway, so a long span was required. The clearance was limited, so SYSTRA proposed an extradosed bridge, with the following spans: 51 - 65.5 - 51m. About half of the bridge is curved in plane view. The deck is nearly the same box-girder prestressed deck as for the typical spans, in order to use the same precast segments formwork for construction optimization, and also for a better architectural continuity. The pylons and the deck are embedded with the main piers. The main span was built by cantilever. |
