Due to the limitations of traditional ice force measurement methods in terms of stability and reliability,and the high sensitivity and anti-interference capabilities of fiber optic sensing technology was given,a fiber optic ice force sensor was developed.The effectiveness of this sensor was evaluated in the context of its application in marine structures.Based on the fundamental principles of fiber optic sensing technology and the design requirements of the ice force sensor,the research,design,and installation processes of the sensor were described in detail,including the design calculations of the elastic element,the selection and arrangement of the fiber optic sensors,and the construction of the data acquisition system to ensure that the precision requirements for ice force measurement were met.A winter field measurement of ice force was conducted at an observation station in the northern Bohai Sea.Field ice force data were successfully collected and analyzed,and the actual monitoring performance of the sensor was evaluated.The experimental results indicate that the system exhibits good stability and reliability in practical applications.The developed fiber optic ice force sensor provides a new reliable technical means for ice force measurement in marine engineering and lays a foundation for further research in structural health monitoring.
