大跨连续刚构桥运营期监测结果分析

Analysis on Monitoring Results of Large-span Continuous Rigid Frame Bridge during Operation Period

通过对东江特大跨连续刚构桥运营期进行定期监测,结合桥梁结构的仿真计算分析,初步探寻连续刚构桥与汽车荷载、砼收缩徐变、温度等影响因素之间的关系,为以后同类型桥的运营监测及养护提供一定的依据。

Based on regular monitoring of the Dongjiang Bridge during operation period, which is a special long continuous rigid frame bridge, combining with simulation analysis of bridge structures, in this paper, the relation-ship among affection factors as loads of rigid frame bridge and vehicles, concrete shrinkage and creep, temperature, has been studied, which can provide reference for monitoring and maintenance of the similar bridges.
