连续梁桥施工监控技术研究

Research on continuous bridge construction monitoring technology

针对一座悬臂施工的连续梁桥的施工过程进行了全面监控,基于有限元软件模拟了大桥施工过程的受力状态,根据受力特性合理设置了主梁标高、应力测点并在施工过程的重要工况进行了监测,成桥后的测试结果表明大桥受力状态满足设计要求。

In view of the comprehensive monitoring of the construction process of continuous beam bridge of a cantilever construction,based on mature finite element software simulated the stress state of bridge construction process,according to the stress characteristics reasonably set the main beam height and stress measurement point,and monitored the important working conditions in construction process,the results test after the bridge was formed showed that the bridge stress state met the design requirements.
