In view of the poor structural stability of port pile foundation at present, the key technology research of port pile foundation construction based on mechanical analysis is put forward. According to the construction characteristics of ports, the settlement-displacement relationship of soil mass on pile side is analyzed. The pile-soil contact model is constructed based on the settlement calculation results of single pile. The ultimate Punching Strength of the bearing layer at the end of the pile is determined by considering the punching failure of the hard bearing layer and the strength failure of the soft underlying layer. Suitable proportional value is obtained by static equilibrium condition calculation, and key technology research of port pile foundation construction based on mechanical analysis is completed. The experimental results show that the soil pressure exertion coefficient of the pile foundation structure designed by the proposed technology is stable, and the change trend of the passive soil pressure coefficient is basically the same as that of the active soil pressure coefficient. It can be verified that the stability of the designed pile foundation structure is significantly improved compared with the structure designed by the comparison methods.
