摘要
内部病害已经成为影响道路结构性能的重要因素之一,及时掌握其状态信息成为道路结构长期安全运行的重要保障。文章概述了道路结构内部病害检测的必要性,简述了光纤传感技术在路面内部裂缝和路基沉降变形监控两个方面的应用。对光纤传感技术进行了介绍,分析了不同类型光纤传感器的适用情况,针对该领域中存在的问题做出了总结,并提出光纤传感器的选择与应用要考虑道路结构实际行为响应、加大现场试验研究力度以提高传感技术的实用性等措施。
The internal disease has become one of the important factors affecting the performance of road structure,and timely grasp of its state information has become an important guarantee for the long-term safe operation of road structure.This paper summarizes the necessity of detecting the internal disease of road structure,and describes the application of optical fiber sensing technology in the monitoring of pavement internal cracks and subgrade settlement deformation.This paper introduces the optical fiber sensing technology,analyzes the application of different types of optical fiber sensors,summarizes the existing problems in this field,and proposes that the selection and application of optical fiber sensors should consider the actual behavior response of road structure and increase the field test research force to improve the practicability of the sensing technology.
