Anchored Suspension Bridge Cross-tension Control

The force control of suspension bridge anchorage cable is the main contents which will be researched.According to the character of suspen- sion bridge anchorage, three questions is solved in this paper on the basis of the construction control experience of The Highway Bridge Of Yichang Yanzhi River.Firstly, an effective method of cable force control is presented in this paper, which has settled the puzzle of cable force accurate operate through fixing a pressure transducer at the behind of the hydraulic jack . Secondly, an exactitude calculation model is founded in this paper.In addition the influence of boundary condition , sag, inclination, flexural rigidity and environment temperature to the cable vibration frequency which make the frequency method could be used to the measurement of cable force.In the end of this paper, a control system of anchorage cable force is developed on the basis of the above research.This system is very steady , credible, high precision and convenient.It is a new and credible method to be used to the force control of sus- pension bridge anchorage cable.In this paper, the conundrum of cable force control has been solved.The fruits are very useful to the development of inland suspension bridge.
