Abstract:Research purposes:The temporary consolidation at top piers is regarded as rigid body in continuous girder cantilever construction. And the calculation theory and method are mature. Whereas, temporary consolidation beside piers should be regarded as elastic body. And the calculation methods about it are insufficient. Through the mechanical analysis of temporary consolidation beside piers, a simple calculation method is proposed and can be applied in various construction conditions.Research conclusions:(1) Simplify the temporary consolidation beside piers as elastic three fulcrums model which is consistent with practical force-baring conditions. (2) Calculation method based on elastic three fulcrums model can be well applied in various construction conditions. (3) Calculation of axial forces temporary consolidation beside piers is well related to their tension-compression stiffness, and we should choose calculation formula based on their tension-compression stiffness and force-baring conditions. (4) The calculation method proposed can be the base and accordance for design of temporary consolidation beside piers in PC cantilever casting girders.
