在前人研究基础上 ,对塔中 号断裂带地层进行岩石力学试验 ,并用相似材料地质力学模拟试验研究塔中 号断裂带在后期应力场作用下演化过程。结果表明 ,塔中 号断裂对塔中地区的地质构造起控制性作用。张裂和剪裂为该区地层的主要破裂机制 ,所产生的裂缝集中发育于中部的奥陶纪和寒武纪地层。
Based on the previous studies, the rock mechanics tests of the Tazhong fault zone strata are carried out. The geomechanical simulation tests of similar materials are used to study the evolution of the Tazhong fault zone under the influence of late stress field. The results show that the Tazhong fault plays a controlling role in the geological structure of Tazhong area. Cracks and shear fractures are the major rupture mechanisms of the strata in the area, and the fractures produced are concentrated in the Ordovician and Cambrian strata in the middle.
