Stress Safety Monitoring in Construction Stage of Wuzhong Yellow River Bridge

摘要

According to the stress monitoring in construction stage of Wuzhong Yellow River Bridge, the determination of stress test methods, the design of stationing scheme, the selection and inbuilt technology of optical fiber strain sensor, the theoretical computational analysis of structure and the processing of measured data are detailedly explored in this paper. A compound technology of optical fiber strain sensor and concrete is introduced, a type of analysis process method of measured data is generalized, a finite element model applicable for structural analysis is built up by using the finite elements analysis software-ANSYS and detailed simulation analysis in the construction stage of Wuzhong Yellow River Bridge is done. The detailed comparison and analysis between theoretically calculated result and measured data is done also. The acquired research result can supply reference for the construction monitoring of the similar kinds of bridge in the future.
