Lateral displacement resisting method for building envelope through PBA construction method

The invention relates to the field of subway station construction, and discloses a PBA construction method enclosure structure lateral displacement resisting method which comprises the following steps that firstly, a plurality of mounting holes penetrating into lower-layer middle pilot tunnels on the same side are drilled in the side walls of two sets of lower-layer side pilot tunnels correspondingly, and the mounting holes are evenly formed in the depth direction of the lower-layer side pilot tunnels at intervals; next, a tubular supporting piece is installed in each set of installation holes, one end of each tubular supporting piece abuts against the side wall of a bottom longitudinal beam in the lower-layer middle pilot tunnel, and the other end of each tubular supporting piece is anchored to a strip-shaped foundation of the lower-layer side pilot tunnel; finally, cement mortar is injected into each set of tubular supporting pieces; according to the lateral displacement resisting method for the building en
