Abstract

Geotechnical engineering is characterized by many uncertainties, including soil material properties, environmental effects, and engineering design and construction, which bring a significant challenge to geotechnical monitoring. However, conventional sensors with several inherent limitations, such as electromagnetic interference, signal loss in long-distance transmission, and low durability in harsh environments cannot fully meet current monitoring needs. Recently, fiber optic sensing technologies have been successfully applied in geotechnical monitoring due to the significant advantages of anti-electromagnetic interference, stable signal long-distance transmission, high durability, high sensitivity, and lightweight, which can be considered an ideal replacement for conventional sensors. In this paper, the working principle of different fiber optic sensing technologies, the development of fiber optic-based sensors, and the recent application status of these sensing technologies for geotechnical monitoring were comprehensively reviewed and discussed in detail. Finally, the challenges and countermeasures of the sensing technologies in geotechnical monitoring were also presented and discussed.

综述了光纤传感技术在岩土工程监测中的应用研究进展

岩土工程具有许多不确定性，包括土壤材料特性、环境影响以及工程设计和施工，这给岩土工程监测带来了重大挑战。然而，传统传感器具有一些固有的局限性，如电磁干扰、长距离传输中的信号损耗以及在恶劣环境中的低耐久性，无法完全满足当前的监测需求。近年来，光纤传感技术因其抗电磁干扰、信号远距离传输稳定、耐久性高、灵敏度高、重量轻等显著优点，已成功应用于岩土工程监测，是传统传感器的理想替代品。本文对不同光纤传感技术的工作原理、基于光纤的传感器的发展以及这些传感技术在岩土工程监测中的应用现状进行了全面回顾和详细讨论。最后，对遥感技术在岩土工程监测中面临的挑战和对策进行了探讨。
