岩石的非均匀性对于其破裂及渗流过程具有显著的影响. 本文提出了用数字图像处理技术表征岩石非均匀性的基本方法, 并通过把该技术实施到岩石破裂过程分析程序 RFPA 中, 来模拟非均匀岩石在外载荷和渗流耦合作用下发生破裂的整个过程. 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.

Abstract: The heterogeneity has significant effect on the failure process and seepage characteristics of rock. A digital image-based (DIB) technique was proposed to characterize and quantify the heterogeneity of rock, and it was implemented into RFPA (Rock failure process analysis) code in order to simulate the complete failure process of rock under both the external loading and fluid pressure. It was shown by numerical simulations that the DIB technique was effective in capturing the rock heterogeneity, and it paved a new way for …
