摘　　要：光纤光栅传感系统在各类工程中应用越来越广泛。针对目前光纤光栅传感系统在PHC管桩中应用的局限性,通过在PHC管桩生产过程中,埋设光纤光栅传感器和光纤导线,进行主要生产环节的传感器成活率测试。验证了在PHC管桩免蒸压技术生产工艺下,光纤光栅传感系统植入PHC管桩是可行的。方便了光纤光栅传感系统在PHC管桩中的应用,并提高了测试精度。首次提出在PHC管桩桩身内植入光纤光栅传感系统的测试方法,给出了管桩接桩时的光纤光栅传感系统穿线管预埋及桩顶端侧面穿线孔预留的方法,既保护了光纤光栅传感系统,又不对接桩造成影响,保证了接桩质量。Fiber grating sensor system is applied widely in engineering. In order to study the application of fiber grating sensor system in PHC pipe piles,fiber Bragg grating（ FBG） sensor and fiber-optic conductors were buried in the molding process, and the survival of sensor was tested in the main production processes. Fiber Bragg grating sensor buried in PHC pile is verified feasible when PHC pile is produced with non-autoclaved technique. The FBG sensing system is convenient to apply in PHC Pile and the test accuracy is improved. It is the first time to propose the testing method of FBG sensing system implanted in PHC Pile. The treatment of fiber grating sensor system at the pile splicing with embedding pipe and hole is put forward,so that the fiber grating sensor system is protected and pile is not affected,then the quality of pile could be ensured.
