Thinking About Rigid Hanger Replacement of the Tied Arch Bridge

XIA Ye-fei;Jiangsu Province Communications Planning And Design Institude Limited Company;  
Due to rigid hanger,it is difficult to get cable force by vibration method.Here we use the simulation calculation and jack tension synthetically to get final constant hanger internal force.Then by batch tensioning and equivalent method,we replace successfully all the hanger through help of the temporary suspender system one by one.Furthermore,the steel strand bundle of extruded cables can sovle effectively small size of the hanger anchor head and improve evidently hanger durability.
