| Abstract: | The surface deformation in many projects belong to the scope of great deformation. In thise paper taking a great deformation of surface as the study subject, the authors use the finite deformation geometry of the nonlinear continuum media mechanics for the analysis of surface deformation. This paper provides the theoretical basis and the data processing method for precise study of the information about the state of surface deformation. |
