摘要
近年来,光纤光栅传感技术在我国发展很快,已经在桥梁、土建等多个领域中得到了应用,但在水工领域的应用还很少.本文结合白鹤梁工程实例,探索该项技术在这一领域应用的可行性.开展的光纤光栅应变、温度传感器在水下工程领域中较大规模的应用研究结果表明:FBG具有很好的防水性能,测试精度高,长期稳定性好,信号传输距离远,为水下结构的长期监测提供了一种可靠有效的手段.
In recent years, FBG sensing technology has been rapidly developed and been used in many fields, such as bridges, building fields ere, but there is few applications in under - water structure projeet. In the paper, in order to discuss the feasibility of FBG sensing technology used in the field, the application in the BaiHeLiang project is introduced that FBG stress and temperature sensors have been used on a large scale in under - water structure project. The results show that FBG sensors have outstanding waterproof capability, high measurement precision, better long- term stability and more remote transmission signal, so FBG sensing technology is a reliant and effectual instrument for under -- water structure project monitoring.
