摘要
川中地区香溪群中的裂缝主要为非构造成因,构造应力仅在一定程度上促进了裂缝网系的发育和扩展。裂缝的形成机理主要有差异压实、重力滑动、溶蚀作用以及构造应力四种。
The fractures of Xiangxi Group in the central part of Sichuan are mostly of untectonic origin. Tectonic stress impells the fractures to develop and expand only to a certain extent. The main mechanisms of formation of the fractures are: differential compaction, gravitational slipping and dssolution.
