Leaning type arch bridge calculation cannot simply use plane pole-system program is simplified, should utilize the space finite element procedure for the determination of arch and beam grid system rigidity[1,3].For this reason, in this paper a built in Jiangmen City Shengli bridge as the background, according to the bridge construction monitoring program, the main research of leaning type arch bridge main arch erected in to complete the bridge construction mechanical behavior during the modeling, and calculation results and measured data were analyzed to discuss ,which has an important theoretical meaning and engineering practicing value.
Fig.1 Vertical plane of the major bridge (cm) 1 Calculation Model The finite element analysis software of MIDAS/Civil are used to simulation analysis on Shengli bridge structure construction process, the main arch rib, leaning arch rib, transverse, longitudinal and transverse beams tied, deck system with 6 degrees of freedom using space beam element model with 3 degrees of freedom; hanger rod space bar element simulation; bridge deck with 6 degrees of freedom using space shell element simulation.
Conclusion Based on the analysis on mechanical behavior during the modeling, the following conclusions are obtained: 1) Based on the finite element software MIDAS/Civil on the Shengli bridge construction process of simulation calculation, and the calculation results and field monitoring numerical results are compared and analyzed, and the result was verified that construction monitoring program basically reasonable 2) Monitoring results and calculation results show main arch rib key section in the process of construction the stress values are less than the allowable stress values, the arch rib alignment, are in the design range alignment requirements, have ensured the successful accomplishment of the construction.
