光纤传感技术在结构工程检测中的应用

Application of Fiber Optic Technology in Structure Engineering Testing

简要介绍了光导纤维及其传感原理 ,对利用光纤传感技术检测钢筋混凝土结构养护期的热应变和温度、结构内部应力应变、结构的振动参数、裂缝宽度和结构整体性估计等方面的方法和原理作了详细分析和讨论 ,综述国内外发展状况。

The fiber optic theory is presented briefly.Then the testing methods and principle of the heat strain and temperature of the conserved RC,the inner stress and strain,the vibration Parameter,the crack and the integrity of the structure with the help of the fiber optic technology are analyzed and discussed particularly.At the same time,the domestic and foreign development is introduced and some problems are brought forward.
