摘要
由于光纤Bragg光栅传感器具有一般传感器不可比拟的优点,其应用越来越广泛,但在道路工程中的应用还不是很多。在对光纤Bragg光栅传感器的机理介绍基础之上,对于该传感技术在路面结构层三向应变场的监测、动水压力的测定、沥青路面车辙的计算预估等方面的应用研究进行了叙述,并采用其他路用性能检测手段,对比了其监测结果。结果发现其应用具有可行性,同时提出一些应用时需要注意的问题,以保证其监测结果的准确性。
Fiber bragg grating sensor is widely used more and more because of some merits that ordinary sensor cannot compare. However, its application in road engineering is not much. Basing on the introduction of mechanism of fiber bragg grating sensor, the applied research of such sensor technology in the matter of monitoring on three - dimensional strain field of pavement structural layer, measurement of dynamic water pressure, and calculation estimate of rut on asphalt pavement is elaborated, detection means on other pavement performance are adopted, and the monitoring results are compared. The results show that it is feasible Meanwhile, issues needing attention are put forward, so as to guarantee the correctness to perform its application. of monitoring results.
