摘要
介绍了光纤法珀(F-P)应变测量系统的基本原理及结构,并将该系统实际应用于大佛寺长江大桥结构应变测量中.测量结果表明,光纤F-P应变测量系统的测量值能够有效地反映桥梁结构混凝土内部受温度影响的应变变化,测量系统运行正常有效.
The basic principle and the composition of optic fiber F- Pstrain measurement system are introduced, and it is practically utilized in the strain measurement of Dafoshi Yangtze River Bridge. The results show that, the acquired data from F- Pstrain measurement system can effectively describe the strain variation upon the temperature change, the measurement system is working sound and effectively.
