摘要：In the cable-beam anchorage structure with tensile anchor plate of cable-stayed bridges, there is obvious stress concentration in the local area and the weld position of the anchor plate, which is prone to plastic failure and leads to the reduction of the bearing capacity of the anchorage zone. In order to analyse the mechanical behaviour and optimize the local structure of the anchorage, the finite element simulation technology is used to study the mechanical performance and bearing capacity of the anchorage. The stress distribution law and transmission path of the anchorage structure are defined, and the influence of structural parameters on mechanical performance is analysed. In order to reduce the stress concentration level and improve the bearing capacity of the anchorage, the optimum structural measures of anchorage structure are put forward.
