[Abstract]:Since there is no end anchor cable in the middle tower to restrain the horizontal displacement of the tower top, the flexibility of the multi-tower cable-stayed bridge is greater than that of the single-tower and double-tower cable-stayed bridge. When a span of the cable-stayed bridge is subjected to live load, the main beam and cable tower will produce great bending moment and displacement. The force on the whole structure is very unfavorable. This paper takes the cable-stayed bridge with three towers of right branch of Ma'anshan Yangtze River Highway Bridge as the engineering background, and synthetically considers the structural characteristics, design theory and construction control of the arch tower, and carries out the tracking simulation calculation of the cable-stayed bridge. Firstly, the calculation model of the whole bridge is established by using the finite element software such as the bridge doctor Midas civil, the whole bridge is checked and the weak link of the design is determined according to the result of the review. Secondly, by analyzing the results of 1:10 arch tower model test, the stress distribution and deformation law of arch tower structure under transverse prestress and cable tension load, as well as the stress distribution and crack of key section determined in integral calculation are obtained. The design results and the overall calculation results are verified. Finally, according to the actual construction situation, the calculation model is adjusted and combined with the construction monitoring, and the simulation calculation of the whole construction process of the cable-stayed bridge is completed. The research provides necessary technical support for the construction of the cable-stayed bridge.
