The invention discloses a calculation method of bridge pile steel sleeve construction additional force, and relates to the technical field of underground engineering. The method comprises the following steps of building a calculation model of steel sleeve construction; calculating the pile end pressure p according to the calculation model; calculating the pile side radial pressure q according to the calculation model; calculating the pile side vertical frictional resistance f according to the calculation model; according to the pile end pressure p, introducing a soil plug height reduction coefficient zeta, and calculating corrected pile end pressure p'; and according to the pile side radial pressure q and the pile side vertical frictional resistance f, introducing four-section correction, and calculating the corrected pile side radial pressure q' and the corrected pile side vertical frictional resistance f'. According to the method, the problem that in the prior art, when the additional force of steel sleeve construction is calculated, the characteristics of steel sleeve sectional construction in actual engineering are neglected, and the influence of the strength of the soil squeezing effect within the steel sleeve construction depth range is ignored, so that the final result and the actual engineering have access to each other is solved.
