摘要
The long-span prestressed concrete continuous girder bridge might occur bottom slab breakup after prestressed tension and cause bridge damaged on practical engineering. In order to reveal this phenomenon, it is necessary to research and analyze the radial and transverse effect of prestressing force to the structure and acquire the causes of bottom slab breakup. Based on one continuous rigid frame bridge in Nanjing, analyze the reasons of bottom slab breakup by establishing finite element model, and put forward reasonable design and construction methods to prevent bottom slab breakup for actual bridges.
