Construction Control Of Self-anchored Suspension Bridge

Self-anchored Suspension Bridge is drawing more and more people's attention because' of kinds of advantadges. As one of difficulties, construction control is drawing people's attention as well.The text study methods and theories of Self-anchored Suspension Bridge construction control ,based on the data of Yiwujiang Bridge. The textual emphases:1. The text puts forward Weak Interference of Displacements of Cable . It describes the situation of displacement of cable during tension. It is said that the relationship between displacement of cable and tension suspenders is well-regulated.2. The text puts forward Near Influence of Suspender Force . It describes the current of Suspender force during tension. It said that the relationship between the force and pulling suspenders is well-regulated.3. The text puts forward Forward Alternately Tension Method. The advantadge of the method is that the tension efficiency is higher than that of single tension. At the same time, the working procedure is pretty simpler, and the compositive efficiency is improved greatly.4. The text puts forward Optimization method for suspender force based on the Optimization Function integrated with Nonlinear Calculation Function . And a example is taken for us to prove the feasibility.5. The moment due to eccentricity between the anchor and the girder influence the bridge greatly; The friction between the cable and the saddle can be worked out by parse,and we have applied the result in the construction.
