Study on Safety Evaluation of Cable-stayed Bridge Based on Inspection of the Main Span Cables' Tension

摘要

This paper studies on the working state and safety performance of the cables, because cables are the principal bearing elements of the cable-stayed bridges. The paper makes a detailed analysis on the main span cables' tension of a bridge over Yellow River and puts forward the safety evaluation. The paper suggests making an analysis on the deformation and tension of the whole bridge according to the cables' tension variation, and taking corresponding project adjustment and structure adjustment measures if necessary.
