引言为了巩固和发展地质力学,近几年我们在实践中证明,在显微层次里岩组分析可以在若干方面作出佐证,说明李四光同志对地质构造—褶皱、断裂应用力学性质作组合分析与个别处理的准确性。在微观方面,我们提出了一些不成熟的意见,扬弃了一些国外的解析和作法,走我们自己的道路,希望同行同志们给予批评指教,我们会在讨论中得出一条和谐的简 Introduction In order to consolidate and develop the geomechanics, in recent years we have proved in practice that the analysis of petrophysical groups at the microscopic level can be corroborated in several aspects. This shows that Comrade Li Siguang made a combined analysis of the mechanical properties of the geological tectonics-folding and fracture, Accuracy of processing. At the microscopic level, we have put forward some unhealthy opinions, abandoned some foreign analyzes and practices, took our own path, and we hope that comrades in the same league will give criticism and advice. We will come to a concise and concise discussion during the discussion
