斜拉-悬吊协作体系桥梁换索加固过程中受力复杂,必须通过全过程监控保证桥梁施工安全,确保成桥后结构受力和线形满足设计要求。以乌江大桥维修加固工程为依托,重点介绍换索过程中塔、梁、索的监控方法、结果分析及索力调整等关键技术。 Cable-Suspension Collaboration System The bridge is subject to complicated forces during cable replacement and reinforcement. It is necessary to ensure the bridge construction safety through the whole process of monitoring and control to ensure that the structural stress and linearity of the bridge after completion of the bridge meet the design requirements. Relying on the maintenance and reinforcement project of Wujiang River Bridge, the key technologies of tower, beam and cable monitoring, result analysis and cable force adjustment are mainly introduced.
