Abstract
According to current application status of FBG sensors in concrete pipe piles
introduce data processing principle of FBG sensors
aiming at most prone to damage part in test
a reliable FBG sensors embedded technology is proposed
combined with field PHC pipe pile vertical static load test
experimental datas are compared with the traditional resistive strain gauge datas.Experimental results show that survival rate of FBG sensors is as high as 97.06 %
test datas are reliable and test precision can satisfy requirement of engineering
FBG sensors can be completely applied to vertical static load tests on PHC pipe piles.
