Determining an active jacking force of a tunneling closely undercrossing existing station, includes: acquiring design parameters of stations, and geological parameters of a construction site; obtaining a stress solution expression of the active jacking force on the existing station to obtain a stress solution of any point in a semi-infinite space under the action of a vertical load, replacing the vertical load with a vertical load acting on the existing station, and obtain a vertical stress solution of the existing station; obtaining a relational expression between the deflection and the stress solution of the existing station; and substituting the stress solution expression of the active jacking force into the relational expression between the deflection and the stress solution of the existing station according to boundary conditions at both ends of a beam on elastic foundation to obtain the active jacking force that controls the deflection of the existing station.
