摘要
岩土工程在施工过程中,其外部环境较为恶劣,且受材料腐化、地质灾害、使用方法及疲劳效应等多重因素的影响,工程结构可能存在开裂变形、地基下沉及稳固性衰减等问题,由此,强化健康评估和安全监测成了迫切需要。针对光纤传感器的高精度、抗干扰及成活率高的优势,文章以光纤传感器的原理及分类为切入点,详细阐述了其在岩土工程应用中的关键性技术问题,并以分布式光纤传感器技术为例分析了其布设方法,以此为岩土工程安全监测提供一定的理论参考。
During the construction process of geotechnical engineering, its external environment is very bad, and geotechnical engineering is affected by multiple factors, such as material corrosion, geological disasters, methods of use and fatigue effects, the engineering structure may have some problems such as cracking, deformation, subsidence of foundation and attenuation of stability, therefore, to strengthen the health assessment and safety monitoring has become an urgent need.In view of the high accuracy of optical fiber sensor, anti-interference and high survival rate advantages anti-interference and high survival rate advantage, this paper takes the principle and classification of fiber optic sensors as the breakthrough point, elaborates its key technical problem in the application of geotechnical engineering, and takes distributed optical fiber sensor technology as an example to analyze its layout method, in order to provide the theory reference for geotechnical engineering safety monitoring.
