According to total compensation composite inversion algorithm, physical parameter identification and inversion of wave time interval are done under the condition of input information of isolated pier in wave force part being unknown. Based on the characteristics of large-diameter piers in shallow water which are affected by wave force and combining with “statistical average method” in probability theory, structural physical parameter identification and wave inversion calculation are done under the condition of unknown wave force. Analysis of numerical values shows that results of structural physical parameter identification cater for accuracy requirements which is feasible for inversion method of parameter identification of large-diameter piers in shallow water with unknown input information thus providing a new method for structural physical parameter identification research of river-spanning and sea-crossing piers affected by wave force and providing references for engineering application.
