Balanced cantilever erection for continuous girder bridges, continuous rigid frame bridges(CRFB) and cable-stayed bridges has been recognized as one of the most efficient methods of building bridges without the needs for falsework.

On the construction technology of bridge double thin-walled high piers;

One large bridge double thin-wall pier scheme optimization and measure

Utilizing structural parameters in original design scheme the deformation,internal force and stress of control cross-section of bridge are calculated and analyzed through change the wall distance of double thin-wall piers.

In the design of the continuous rigid frame bridge with double thin-wall piers,the reasonable selecting of parameters is very important to the bridge.

According to the condition of deformation compatibility,the author establishes a relation between the load on the coping of pier and the single inner force of the double thin wall pier.
