LI Zhuo-qin

Abstract

Large-span steel truss arch bridge utilizes crawler crane for arch rib installment,which is not only economical,but also safe,and a further improvement of cable lifting steel wire stayed knotting construction technique without support. According to the introduction of Chongqing Chaotianmen Great Bridge construction method,the cable lifting steel wire stayed knotting construction technique is detailedly analyzed,which can provide some reference for similar large-span arch bridges.
