Linear monitoring for continuous rigid frame bridge in Jinghe section of Xichangfeng highway

With the practical example of the Jinghe especially large bridge project,the paper introduces the bridge calculation models,the main rigid deflection test section and the arrangement of measuring points,and analyzes the linear monitoring results of the main bridge closure section.At last,the conclusion has been drawn,with a referential value for similar constructions of highway long span continuous rigid frame bridge,and worthy of wide popularization and application.
