Foundation pit excavation deformation control process based on inverted arch reinforcement

The invention discloses a foundation pit excavation deformation control technology based on inverted arch reinforcement, and belongs to the technical field of foundation pit excavation deformation control. The foundation pit excavation deformation control technology comprises the steps that according to the width and depth of a foundation pit to be excavated, the foundation pit periphery sinking-upheaval damage range is determined; determining an upper arch axis boundary and a lower arch axis boundary of an inverted arch reinforcing area range required by a bottom plate of the foundation pit according to the width and the depth of a sinking-upheaval damage range at the periphery of the foundation pit; according to the range of the inverted arch reinforcing area, reinforcing holes are evenly distributed at intervals along the ground surface, and the reinforcing depth range of the reinforcing holes is determined; the surrounding stratum is subjected to inverted arch reinforcement along the range of the foundati
