ABSTRACT
Relying on the Yongsheng Bridge on the Suiman Highway from Mudanjiang to Suiyang as the engineering background, the common structural diseases of the bridges are collected and sorted out, and the causes of the diseases are summarized. The finite element model simulation analysis of the crack is carried out to study the influence of the existing U-shaped crack characteristic parameters of the T-beam on the bridge stiffness. It provides a theoretical basis for the research of bridge crack and maintenance.
