- Abstract
In order to explore the influence of the distribution of cracks in the rock on the stability of the rock, X-ray diffraction test and electron microscope scanning test were carried out. It was found that the cracks are highly developed under the microscopic view, and micro-cracks can be clearly observed. difficult to observe directly. PFC2D can solve this problem very well. It can generate fractures with different inclination angles and different numbers of different total lengths respectively; explore its influence on the compressive strength of rocks, and observe the development process of micro-fractures and the macro-fractures and micro-fractures after complete crushing. It is found that the inclination angle is linearly related to the compressive strength, and the micro-cracks generally have an X-shaped distribution after complete crushing.
