Inclined side formwork erecting method for distorted surface bare concrete inclined wall

The invention discloses an inclined side formwork erecting method for a distorted-surface bare concrete inclined wall. The method comprises the steps that three-dimensional modeling is conducted on the distorted-surface bare concrete inclined wall to form a three-dimensional model; finding out at least three buses with different elevations from the three-dimensional model along the horizontal direction; manufacturing at least three back ridges according to the shapes and the lengths of the at least three buses in an equal proportion; a mounting frame is arranged on the inclined side of the design position of the distorted surface bare concrete inclined wall in a supporting mode; respectively fixing the at least three back ridges on the mounting rack according to the positions of the at least three buses in the three-dimensional model; a plurality of pipe fittings are provided, each pipe fitting is connected with all the back ridges in series, and finally the twisted face framework is formed; according to the
