Pavements always play a predominant role in transportation. Health monitoring of pavements is becoming more and more significant, as frequently suffering from cracks, rutting, and slippage renders them prematurely out of service. Effective and reliable sensing elements are thus in high demand to make prognosis on the mechanical properties and occurrence of damage to pavements. Therefore, in this paper, various types of functionality enhancement of industrialized optical fiber sensors for pavement monitoring are developed, with the corresponding operational principles clarified in theory and the performance double checked by basic experiments. Furthermore, a self-healing optical fiber sensing network system is adopted to accomplish full-scale monitoring of pavements. The application of optical fiber sensors assembly and self-healing network system in pavement has been carried out to validate the feasibility. It has been proved that the research in this article provides a valuable method and meaningful guidance for the integrity monitoring of civil structures, especially pavements.
路面在交通运输中始终发挥着主导作用。路面健康监测正变得越来越重要,因为频繁出现的裂缝、车辙和滑移会使其过早地失去服务功能。因此,迫切需要有效且可靠的传感元件来预测路面的力学性能和损伤情况。为此,本文开展了用于路面监测的工业化光纤传感器的各类功能增强研究,从理论上阐明了相应的工作原理,并通过基础实验对性能进行了双重验证。此外,采用了一种自修复光纤传感网络系统来实现对路面的全面监测。开展了光纤传感器组件和自修复网络系统在路面中的应用以验证其可行性。结果表明,本文的研究为土木结构尤其是路面的完整性监测提供了一种有价值的方法和有意义的指导。
