针对土木工程领域中光纤传感器与混凝土结构的相容性问题 ,在理论分析和研究的基础上 ,提出一系列提高二者相容性的方法 ,并研制了一种新型的光纤传感器。实验研究表明 ,采用新型光纤传感结构和环氧保护层方案 ,不仅使传感器能适应恶劣的施工环境 ,而且能较好地实现对裂纹产生、扩展、断裂的监测 ,并在大变形情况下传感器不失效 ,具有较好的相容性 ,能够满足实际工程的要求 Aiming at the compatibility between optical fiber sensor and concrete structure in the field of civil engineering, a series of methods to improve their compatibility are put forward on the basis of theoretical analysis and research, and a new type of optical fiber sensor is developed. Experimental results show that the new fiber sensing structure and epoxy protective layer scheme can not only adapt the sensor to harsh construction environment, but also monitor the generation, propagation and fracture of the crack well. In the case of large deformation, the sensor Not failure, with good compatibility, to meet the requirements of the actual project
