【 摘 要 】

According to special production processes of PHC pipe piles, the difficulties in monitoring them are clarified, and this problem can be solved by FBG sensors by virtue of their good performances. Based on the working principle of FBG, the calculation method of the pile under axial load is deduced. By means of engineering example, the processes of monitoring the axial force of the PHC piles by FBG sensors was introduced. The result shows that the installation methods and protective measures are feasible and can provide reference to similar projects. At the same time, the test data is analysed and the process of the axial force of the pile body is explained.
