Construction Monitoring Research Of Prestressed Concrete Rigid-frame Structure Combination Of Continuous Beam Bridge

Long-span prestressed concrete rigid-frame structure combination of continuous beam bridge win widely used in bridge engineering, in order to ensure the long-span prestressed concrete rigid-frame structure combination of continuous beam bridge construction safety and the bridge of the linear and internal force meet the specification requirements, the construction monitoring should be carried on. So for prestressed concrete rigid frame combination of continuous beam bridge construction control work has important engineering application value. This paper, taking zheng zhou to shao lin highway road connecting sailing south-to-north water diversion bridge as engineering example to do the research on bridge construction monitoring, mainly do the following:1.Using the finite element software Midas/Civil build the main line bridge of zheng zhou to shao lin highway road connecting sailing south-to-north water diversion bridge, long-span prestressed concrete rigid-frame structure combination of continuous beam bridge finite element calculation model, according to the actual material properties and boundary conditions of the bridge to modify the calculation model in order to obtain conformity with the practical situation of bridge finite element model.2. According to the established bridge finite element model to do the analysis of the whole construction procedure,the results can provide theoretical basis for the development of the construction monitoring schemes and setting up the bridge arch measurements.3. Adaptive the self-adaptation control method to proceed the main bridge construction control of zheng zhou to shao lin highway road connecting sailing south-to-north water diversion bridge, analysis the bridge site of the measured data and theoretical data, distinguish and correct the calculation model parameter in order to let the theoretical calculation model and bridge continuously to coincide with the actual construction process, so as to guide the bridge construction.4. Through to analysis the measured data and theoretical data of the zheng zhou to shao lin highway road connecting sailing south-to-north water diversion bridge,comprehensive understanding the state of the stress and line under the current situation, by releasing construction monitoring instruction, guide the bridge construction of the nest phase, finally ensure the construction safety and bridge meet specification requirements of the zheng zhou to shao lin highway road connecting sailing south-to-north water diversion bridge.
