Cable Force Monitoring Of Inclined Tower Cable-Stayed Bridge Without Back-Stay In Constructing

Bridge construction control is security assurances of bridge constructing. It is more and more important that the cable force monitoring for alignment and mechanical performance of cable-stayed bridge in the construction of large-span bridge. The bridge construction emulating analysis take a key role with certain precision for the construction of bridge and design state by the reasonable model and the effective structure analysis method. So control preliminary tensioning force and provide effective controls parameter for the structure computation and construction through the emulating calculation. It also provides a instruction for further construction.According to the construction course and finished dead state of the inclined tower cable-stayed bridge without back stay at Tongling Road in Hefei and combining the modern theory and method of the bridge construction control mentioned in this paper, established a space model by large-scale general finite element software ANSYS. It can obtain some valuable result by emulating analysis of the bridge which is under the construction course and finished dead state. It can provide an instruction for the Tongling Road bridge with the result and construction job site monitoring data. At the same time, the theme provides a reference for using large-scale general finite element software to calculate this kind of bridge.
