In order to ensure the safety of the bollard structure,we propose a safety evaluation method for the bollard structure based on standard mooring force inversion,take the mooring force under the fixed mooring height and the mooring angle as the standard,analyze the influence of mooring force on the surface strain of the bollard,apply the surface strain of the bollard as a parameter to characterize the mooring force,and establish the standard mooring force inversion model of the bollard.According to the existing bollard structure,we use the finite element method to analyze the surface strain distribution characteristics of the bollard structure,select the finite-point strain inversion standard mooring force,and compare with the finite element simulation results.The results show that the inversion results have high precision,which can monitor the force characteristics of the bollard under complex mooring conditions.Comparing the standard mooring force with the design cable force can realize the safety evaluation of the bollard structure.
