Starting from the geomechanical viewpoint, an analysis is made of the structural examples investigated in Jiangxi, Anhui and Sichuan. According to changes of both regional and local structural stress fields induced by mechanism of folding and specific terrain condition, as well as the behaviour of mechanical property of rocks, the transformation of mechanical nature of compressive fracture plane is illustrated. By transformation is here meant a conversion of compressive nature into tensile one.Summing up the cause of transformation of compressive plane discussed above and basing on theoretical studies, we have stressed the importance of changes of regional structural stress field caused by relevant tectonic system. The experiments of photo-elastisity concerned are also described.From the transformation of the mechanical nature of compressive fracture plane, one can trace the action of stress within the structural plane and the source of tectonic forces, and from it one can recognize the mechanical nature of structural planes as well as the type of tectonic system.
