本文对斜列式构造断裂的地质条件作了一般概述,着重对偏光显微镜下观察的微观特征作了描述。宏观与微观的结果是一致的,尽管实际观察到的现象相当复杂,但是它们的形成机理可以通过模拟试验来再现。本文在第三部分对模拟试验的结果做了说明。遗过上述研究,为今后进一步研究微裂隙的生长规律以及微裂隙在岩体变形中的作用打下基础。 This paper gives a general overview of the geological conditions of the faulted tectonic fractures, focusing on the microscopic features observed under the polarizing microscope. The macroscopic and microscopic results are consistent. Although the observed phenomena are quite complex, their formation mechanism can be reproduced through simulation experiments. In the third part of this paper, the results of simulation tests are explained. The above studies have laid the foundation for further research on the growth law of micro-fissures and the role of micro-fissures in rock mass deformation.
