摘要
针对土木工程的特点和对监测技术的要求,总结了近年来国内外光纤监测技术的应用现状和问题所在,阐述了光纤监测技术的发展方向,并对此技术在土木工程领域的应用前景进行了展望.
This paper introduces the characteristics and classifications of fiber optic monitoring technology,and focuses on the working principles of two representative sensors —— SOFO system for monitoring displacement and fiber Bragg grating sensor for monitoring stress variation.Based on the characteristics and requirements for monitoring technology in civil engineering,the latest applications and existing problems of fiber optic monitoring technology both domestically and abroad are summarized.Finally,this paper points out the perspective and future tendency of fiber optic sensing techniques in civil engineering.
