中文摘要：
光纤应变传感器已在混凝土结构的健康监测中获得了广泛应用，但传感器的封装和保护技术还不够成熟，直接影响了工作表现。在此对用于混凝土结构的光纤应变传感器现有的封装和保护技术进行了全面的综述，深化了对传感器的封装和保护问题的认识，进而指明了耐用性问题是封装技术中有待解决的关键问题，同时对埋入式布设的传感器的保护技术还需要进一步的研究。
英文摘要：
Optical fiber strain sensors have been widely used in the health monitoring of concrete structures.However,the encapsulation and protection techniques of optical fiber strain sensors were not mature enough until now.The performance of sensors was affected directly by these two factors.In order to promote the solution of this problem,the existing encapsulation and protection techniques of optical fiber strain sensors were roundly summarized.Based on the summary and analysis ,durability problem was pointed out as the pivotal problem needed to be solved in future.Moreover, the sensor protection technique was pointed out to be needed to develop further.
