Based on the combination of spatial auto-search method and least-squares method in modern control theory, “Spatial Auto-Tuning and Optimized Cable Method” was introduced. This method has the advantages of considering geometric nonlinearity, bandwidth optimization, reasonable cable force optimization and calculation Efficiency and high efficiency. A linear and geometric nonlinear finite element simulation software is developed to establish and develop a reasonable long-haul cable tension of long-span cable-stayed bridge with object-oriented C + +. The second Nanjing Yangtze River Bridge is taken as an example Bridge Simulation Analysis
