Application of FBG sensing technology in lateral load tests on precast concrete piles

In view of the existing issues of FBG sensing technology in precast concrete piles, a buring technology of FBG sensors is proposed and successfully applied to the lateral load tests on pre-tensioned prestressed concrete pile s. The experimental results show that the FBG sensors possess a high survival rate, reliable test data and satisfactory accuracy. The FBG sensing technology can be applied to load tests on the precast concrete piles.
