摘要
沉积岩岩石结构对裂缝形成起着关键性的作用,影响裂缝形成的岩石结构因素包括碎屑颗粒,胶结物,碎屑颗粒与胶结物组合,孔隙度以及岩石结构的非均质性。前人研究成果主要存在没有考虑成岩的动态性,以及相同应力条件下的研究薄弱的问题。
The structure of sedimentary rock plays an important role for crack formation. The factors affecting crack formation are rock granule, cement, compound of rock granule and cement, porosity and heterogeneity of rock structure. The disadvantage of previous work in the field is leaving the dynamic diagnosis and the comprehen- sive of factors affecting crack formation when on the same stress condition is limited out of consideration.
