Overhead vertical wharfs have become one of the main structural types of wharves in the upper reaches of the Yangtze River in recent years.Due to their large number of components，complex external damage factors and lack of effective means to know the damage，many wharves are in sub-health service status.As the key component of the whole wharf structure，the pile foundation is an important“window”to“peep”the stress state of wharf structure and the effects of external damage inducement.By constructing a neural network inversion model to analyze the collected finite element calculation data，a simplified calculation model is established using Python-MANSYS，and the applicability of the simplified calculation model is verified by comparison with the solid element model.The data sample space of parametric analysis is obtained by sampling，and the data needed by inversion model is extracted by dimension reduction.On this basis，the relevant parameters of the main damage inducement are inverted，and the inversion results and model performance are analyzed.
