A method for controlling engineering projection deformation includes: calculating, based on known coordinates of an engineering key region, a change rate of a length deformation function per kilometer in a first direction caused by a height difference of the engineering key region and a change rate of the length deformation function per kilometer in the first direction caused by a distance from a central meridian of a Gaussian projection zone of the engineering key region; solving a distance between a meridian where a center of the engineering key region is located and a new central meridian; solving an elevation of a compensation projection plane; and performing comprehensive projection deformation compensation based on the elevation of the compensation projection plane and the distance between the meridian where the center of the engineering key region is located and the new central meridian, so as to realize the controlling of engineering projection deformation.
