岩石细观尺度微损伤识别方法及运用

摘要

Based on the 2D and 3D geometric features related theory in stereology,this paper set up 3D geometry information acquisition parame-ters,basis on this taking the marble meso-scale micro cracks as the research object,gained the characteristics of micro crack spacing to the gener-alized limit distribution variable parameters,and got the damage development in a certain stress range relatively quickly.%基于体视学中二三维几何特征相关理论，建立起三维几何信息获取参数，在此基础上以大理岩细观尺度微裂纹为研究对象，得到了微裂纹间距服从变参数的广义极限分布这一特征，并得到损伤发展在某应力区间较为迅速的结论。
