预应力大跨度连续刚构桥线形监控的实例分析

Case Analysis of Linear Monitoring for Prestressed Long-span Continuous Rigid-framed Bridge

将现有桥梁线形监控理论应用于具体工程项目的施工控制中,结合厂溪特大桥的监控实例综合分析了大跨度预应力连续刚构桥的线形监控要点,阐述了连续刚构桥的监控目的、施工方法及线形监控的组织措施,并对线形监控数据的成果进行了分析。本研究对同类大跨度连续刚构桥施工质量、进度与安全的控制有较好的借鉴作用。

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 organ- ization measures of continuous rigid frame bridge are described, Finally the data of linear monitoring are discussed. The modem linear supervision theory on bridge is applied to construction control of specific projects, which offers reference for similar large-span continu- ous rigid-framed bridge.
