地表位移场的大变形应变参数估计

An Assessment of Great Deformation Strain Parameters in Surface Displacement Field

许多工程的地表变形属于大变形范畴。本文以地表大变形为研究对象，把非线性连续介质力学的有限变形几何学应用到地表变形分析中，为精确研究地表变形状态信息提供了理论依据和数据处理方法。

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.
