A structural health monitoring system by fiber Bragg grating (FBG) sensing technology was installed on 8 # berthing pier of cylinder caisson in a new 300,000 DWT crude oil berth pier of Dalian Port. The system can realize the timely strain monitoring and timely cumulative damage identification of the structure. By analyzing the monitoring data of 8# cylinder caisson under wave load, this paper gives the strain rules and provides the reference for the safety assessment. The study results also have pratical significance on similar structures’ further research.
