    Compared to common fiber Bragg grating (FBG) strain sensor, the FBG strain sensor with low temperature sensitivity has low sensitivity to temperature and high sensitivity to strain. We apply the FBG strain sensors with low temperature sensitivity to static pressure PHC pipe pile penetration test, and monitor the variations of force of pile shaft, toe resistance of pile, and side resistance of pile during the static pressure penetration of the PHC pipe pile. The experimental results indicate that application of FBG sensor with low temperature sensitivity on monitoring static pressure PHC pipe pile during penetration process is suitable, which provides a new testing device for monitoring and analyzing on static pressure PHC pipe pile during penetration process.
