Abstract:Aiming at the problem of safety evaluation caused by structural damage of high-piled wharf,the safety evaluation indicators of the high-pile wharf structure are divided into the horizontal displacement of the macroscopic level,the top angle of the pile top and the pile strain based on the microscopic level.Based on the engineering practice,the finite element analysis model of the high-pile wharf structure is established and compared with the measured dynamic characteristics data.Combined with the finite element model and probability method,the safety evaluation indicators and their sensitivity laws of high-piled wharf structure are studied.It is concluded that the macroscopic safety index is highly correlated with the structural parameters,strength parameters and soil parameters of the pile,while the microscopic safety index is only sensitive to the effective cross-section area and local strength of the pile.The research results can provide a basis for structural damage warning and state assessment of high-pile wharf.
