The invention provides a shield forming tunnel local axis ultralimit treatment method. The shield forming tunnel local axis ultralimit treatment method includes the steps that after shield tunnel forming, the deviating direction of a pipe piece ring in the annular direction of a shield tunnel and the deviating amount corresponding to the deviating direction are measured; according to the deviating direction and the deviating amount, a deviating pipe piece is determined; according to the deviating pipe piece, a correcting pipe piece symmetrical about the deviating pipe piece relative to the axis of the shied tunnel is determined; a correcting space is formed on the side, close to a soil body, of the correcting pipe piece; and on the side, close to the soil body, of the deviating pipe piece, first-time grouting construction is performed, so that the pushing force generated due to the first-time grouting construction is used for making the pipe piece ring corresponding to the deviating pipe piece move to the correcting space. Due to the method, the axis of the pipe piece ring is adjusted to the set axis position, and the structural safety of the shield tunnel and the safe operation of a subway are guaranteed.
