Paper Abstract

A new kind of FRP (Fiber Reinforced Polymer) packaged FBG temperature sensor is developed, and its installation technique has also been studied. The experimental results show that this kind of sensor has good linearity, high accuracy. and high sensitivity. During the construction of the Third Nanjing Yangtze Bridge they were applied to monitor the temperature distribution of the mass concrete. The monitoring results of temperature distribution and its changes with time, environmental temperature, setting retarder, and cooling water agree well with that from experience and qualitative analysis. The practical application shows that the FRY-packaged FBG temperature sensors are proper to be used in temperature monitoring in mass concrete structures.
