Abstract
This paper discusses the cause and influence of the rectification of the tied concrete-filled steel tubular arch bridge suspender of high-speed railway and confirms the differences of suspender tensile forces measured in different periods. The finite element program MIDAS/Civil is used to establish the spatial finite element calculating models of the concrete filled steel tubular arch bridge and the measured suspender tensile force is used to define the corresponding state of the arch bridge by way of successive iterations. The influence of suspender rectification on the safety of bridge structure and train operation is analyzed and specific operation suggestions are offered. The calculating results can be used to guide suspender rectification of arch bridges and provide adoptable theories and practical references for the construction of similar bridges.关键词
