根据库伦剪破裂准则和非线性断裂准则,通过对节理的系统研究定量确定山西晋城成庄矿区存在三期古构造应力场。在前两期古构造应力场作用下,古应力高值区对应于以褶皱与断层作用为标志的宏观强变形区,但与晚期古构造应力场配套的褶皱断裂不发育,则可能是古构造应力较小所致。另外,对比现今构造应力场,随时间的演变主应力表现为先增强后减弱的变化趋势。 Based on the Coulomb shear failure criterion and the nonlinear fracture criterion, a systematic study of the joints was used to quantitatively determine the existence of the third stage palaeotectonic stress field in Chengzhuang, Jincheng, Shanxi. Under the palaeotectonic stress field of the first two periods, the area of ​​high paleo-stress corresponds to the macroscopic strong deformation zone marked by fold and fault, but the fold fracture associated with the late paleo-tectonic stress field is undeveloped and may be paleotectonic Due to the smaller stress. In addition, compared with the current tectonic stress field, the main stress of the evolution over time shows the trend of first increasing and then decreasing.
