It was shown by numerical simulations that the DIB technique was effective in capturing the rock heterogeneity, and it paved a new way for quantifying the effect of local heterogeneity on macroscopic failure process and seepage characteristics.

• 结果表明，基于数字图像的技术是表征岩石细观非均匀性的一种有效方法，为研究非均匀性对于岩石破裂过程及渗流特性的影响提供了一个重要的手段。
