Study on an Arch Bridge Cable Technology and the Stability of the Main Arch Construction

摘要

This paper introduces the great Ninghe bridge main arch of non support cable hoisting process. And it is the main arch cantilever stage calm and stability of wind condition analysis theory, method and conclusion. Analysis shows the main arch construction stability, which not only considers the tower, stability of the main arch, but also considers the safety factor of cable, cable, and safety and stability of cantilever erection by cable breaking force control.
