摘　　要：文章以镇江市解放桥维修加固设计为例,介绍钢筋混凝土V形墩刚架桥的常见病害,指出微弯板边界条件的变化是病害的首要原因。根据计算结果,对刚架桥微弯板及主梁提出维修加固措施,可供以后类似工程设计参考。Taking the maintenance and reinforcement design of Zhenjiang Jiefang Bridge as an example,this paper introduces the common diseases of reinforced concrete V-shaped pier rigid frame bridge,and points out that the change of slight bending slab boundary condition is the primary cause of the diseases.According to the calculation results,the maintenance and reinforcement measures are put forward for the slight bending slab and main beam of rigid frame bridge,which can provide reference for similar engineering design in the future.
