In recent years our country bridge construction rapidly expand,the great span steel pipe concretes arched bridge by its beautiful modelling and the reasonable structure,obtained the massive utilization in the project.More and more steel pipe concretes arched bridge's construction uses the hoisting jack steel stranded wire to pull the buckle to hang the law slanting,and develops fast uses the fixed-length buckle rope law to carry on the arch rib the construction.This hoisting's job practice,must calculate precisely buckles Tension,guaranteed that the bridge and linear satisfies the design requirements in Cheng Qiaohou structure stress.The article widely is collecting the great span steel pipe concretes arch rib hoisting construction to have in the material foundation,explored the hoisting jack to pull the buckle to hang the law construction slanting the characteristic,summarized and has compared the present commonly used reasonable buckle Tension computational method; The ground-to-air steel pipe stiffness skeleton's non-support cable hoisting method carries on the inquisition,summarized has obtained the fixed-length buckle rope law construction merit and the general computation pattern,as well as optimization design mentality and computation theory,multiple optimized computing modes and so on.Unifies the Wu Gorge Wuhan Bridge,the Mt.Huangshan too Pinghu bridge,Hunan bushes street bridge and so on three especially big steel pipe concretes arched bridge is the example,pulled the reasonable buckle Tension's computation which to the steel pipe concretes arched bridge arch rib hoisting jack the buckle hung in the law construction to carry on slanting searched analyzes,has carried on the thorough inquisition to the fixed-length buckle rope's method computation and the optimization design method.Obtains take the reasonable arch spool thread as objective function's optimization computation model raises the value in advance,to arched spool thread's control to achieve the very good effect,thus it can be seen,the fixed-length buckle rope law construction became in the determination steel pipe arch rib hoisting arches the condition aspect is reasonably effective.
