Multi-Projection Surface Deformation Control Method Based on Elevation Naturalization Model

Aiming at the engineering characteristics of the plateau region, a multi-projection surface deformation control method based on elevation naturalization model is proposed. Firstly, the elevation naturalization model calculus and the elevation tolerance are determined. Then, according to the difference between the offset projection surface and the construction work section set by the project section, the construction lofting work is carried out; the projection surface setting in the elevation tolerance, the setting of the single transition projection surface, and the multiple transitions are specifically divided into the setting of the projection surface. The method can ensure the accuracy of the lofting measurement of the project with high efficiency, and can better control the elevation and deformation of the engineering.
