本文概述了为提高对高应力下岩石断裂过程的认识而进行的研究。通过室内模型试验研究了裂缝的起裂和扩展过程，并将所得结果用于数值模型DIGS的标定和验证。这是基于位移不连续性。迄今为止所获得的结果表明，尽管实验结果和数值模拟之间存在总体相似性，但需要对实验程序和DIGS进行改进，以详细了解剪切带取向和拉伸断裂的机理
This paper presents an overview of the research that has been carriecI out to improve the understanding of the fracture processes occurring in rock under high levels of stress. The onset and growth of fractures are studied by means of laboratory model testing, and the results obtained are used in the calibration and validation of the numerical model DIGS. which is based on displacement discontinuity. The results obtained so far have shown that, while there are overall simJlarities between the experimental results and the numerical simulations, improvements to the experimental procedures and the DIGS are required for a detailed mechanistic understanding of shear-band orientations and extension fractures
