| Abstract: | A curve rigid frame bridge in Guangzhou is taken for an example,the influences of self-weight,the load of construction hanging basket,pre-stress,shrinkage and creep,on camber of large-span curved continuous rigid frame bridges with different curve radius in construction are analyzed in this paper.The reserch works provide a scientific proposal for setting pre-arched of large-span curved continuous rigid frame bridges in the construction. |
