Space Plane Single Tower Cable Suspension Bridge Structural Design Of The Main Saddle

In this paper, the structural form of suspension bridge, suspension bridge from the development of domestic and international overview, an overview of the development and evolution of suspension bridge.Bridge the nation's first large-scale spatial cable suspension bridge design and construction of the corresponding little experience. The bridge design is more creative, are complex and difficult structural structure treatment, there are many design, fabrication and installation difficulties. The bridge structure for the full performance of the modern bridge and the current scientific and technical achievements, the big difficulty of construction, high-tech, the integration of architectural aesthetics in bridge structural integrity being. The construction of this bridge the technical difficulties encountered in the country is rare.Papers for this bridge is unique, for further comprehensive analysis focused on the main saddle full of local analysis. Analysis of the process requires the preliminary calculation model, theoretical assumptions, the design load are compared to establish a more reasonable, more accurate calculation of the basic model for calculation correctness and precision in future.In addition, the research process in addition to calculations, some in association with the specific requirements of the necessary tests. The numerical results and experimental data are compared, to more accurately obtain the actual structure of the loading force, the experimental data can also adjust the calculation of a reasonable model for further analysis, and strengthen local structures such issues into consideration.Paper on space and construction of cable suspension bridge, cable systems and space for the most important elements of the structure calculation and analysis and the main saddle structure improved, and made all kinds of tests. For the bridge design, site construction and monitoring provides a theoretical basis and experimental data for the smooth progress of construction provide a strong foundation.Bridge load test results show that the bridge structure and stress state of linear analysis and design of the forecasting results are consistent, the structure of main bearing member and the node design is reasonable.Results of the study design and construction of the bridge has been successfully applied in order to ensure the safety of the bridge construction and operations and create national quality project provides an important technical support, at the same time in the future construction of similar bridges accumulated valuable data and can draw experience, has broad application prospects.
