自从连续介质力学的变形椭球概念由贝克引入地质学领域以后,这概念在构造地质工作中应用颇广,而且常被称为应变椭球。构造地质学当它研究断裂、褶皱、节理与劈理等成因,或依据这些结构要素去确定地块相对运动方向、分析地块变形规律、判断地块所受外力情况的时候,往往定性地 Since the concept of the deformed ellipsoid of continuum mechanics was introduced by Baker to the field of geology, this concept has been widely used in structural geology work and is often referred to as a strain ellipsoid. Structural Geology When it studies fractures, folds, joints, and caving, or based on these structural elements to determine the direction of relative movement of blocks, analyze the laws of block deformation, and determine the external forces of the block, it is often qualitative.
