| Abstract: | Combining with the monitoring case for Changxi Giant Bridge,the main points of linear monitoring for large-span-prestress continuous rigid-framed bridge are analyzed,and the monitoring purposes are elaborated,the construction methods and the organization measures of continuous rigid frame bridge are described.Finally the data of linear monitoring are discussed.The modern linear supervision theory on bridge is applied to construction control of specific projects,which offers reference for similar large-span continuous rigid-framed bridge. |
