Long-span Prestressed Concrete Suspension Bridge Construction Control

Modern structure analysis theory,material intensity,computer technique and construction means progress cause to development greatly of the big suspension bridge in 20th century. The span of the longest suspension bridge is 1991m. In the wake of suspension bridge broadening of stretch, the calculation theory also through early phase the elasticity theory develops up the finite element theory now , and the computational result is more exact. In practice of the suspension bridge construction control , the geometric control of main cable is such core substance, and it also is the main substance of construction control calculation. As to the short-span suspension bridge in little span, the numerical analysis method may be used for construction control calculation simply, and precision of calculation by numerical analysis method correspond to it by the finite element theory, meeting the demand of the construction control.History of the suspension bridge construction control have ten years, yet be the different defects. Through implement of the azhihe bridge construction control and analysis the puzzle of the suspension bridge construction control, the thesis propose the material modification idea of suspension bridge construction control which base on the existing technical, and offer reference to staff of the suspension bridge construction control in the days to come.
