In view of the uncertainty of the parameters of the pile foundation model,a method of parameter inversion identification for pile foundation model was proposed.Taking the measuring point sand the tapping points as noise factors,comprehensively considering the impact of the acceleration response on the inversion results at different measuring points and tapping conditions in the model,using multiple information fusion,the score values were merged into aunique parameter inversion to identify the targetre sponse value.The research results show that the inversion curve obtained by this method has a good fit with the simu- lation curve.This study provides a reference to parameter in version identification for the pile foundation model.
