Discontinuities or weakness planes are those structural features which separate intact rock blocks within a rock mass. 不连续面或弱面指在岩体内分割完整岩石的那些构造形迹。
This paper describes a new approach to formation of polyhedral rock blocks by intersection of plane discontinuities in the rock mass. 描述了通过岩体中不连续面交叉形成多面块体的一种新方法。
