【 摘 要 】

The great structural deformation and inner force will impact the normal use of the bridge, even endanger its safety. Base on it, the paper presents the theoretical analysis method of through concrete-filled steel tube arch bridge, and produce the monitoring methods of the structure deformation, takes a continuous through concrete-filled steel tube arch bridge in Guangzhou as an engineering example, the settlement, three-dimensional deformation of the pier top and the arch rib are monitored in detail. The results show that theoretical calculation are consistent with the measured value in general trend, the theoretical analysis methods and monitoring scheme of structural deformation adopted in this case can have some guiding significance to the similar bridges.
