摘要 研究了光纤Bragg光栅在钢筋混凝土结构应变监测中的应用。对其应变、温度灵敏系数进行标定 ,将其埋设在钢筋混凝土梁内 ,实现对结构内部应变的监测 ,并对其工作状态做出评价。实验结果与理论值、传统监测手段监测结果一致。研制出一种钢管封装Bragg光栅温度传感器监测温度 ,对光纤Bragg光栅的应变与温度的同时测量进行了研究。 The application of fiber Bragg grating(FBG)used in strain monitoring of reinforced concrete structure is studied. Strain coefficient and temperature coefficient were obtained. Static test of reinforced concrete beam equiped with FBG was done in order to study whose distinct sensing ability and monitor strains of the beam. A kind of steel tube packaged FBG was made to monitor the temperature only in order to study simultaneous measurement of strain and temperature.
