A-shaped single-tower cable-stayed bridge space construction monitoring method
The invention discloses a space construction monitoring method for an A-shaped single-tower cable-stayed bridge. The method comprises the steps of structural analysis, measuring point arrangement, stay cable force monitoring, linear monitoring, temperature field monitoring and construction condition monitoring. Wherein the structural analysis comprises early-stage structural analysis and monitoring process real-time analysis, the early-stage analysis determines theoretical control data through simulation calculation of the construction process, and the safety of the structure is analyzed and verified through the use load in the bridge forming stage; and the monitoring process real-time analysis is to compare an early-stage analysis result with a measured value in an engineering construction period, and provide accurate control data for specific operation of a next construction link according to error analysis and an optimal control theory.
