| Abstract: | Seepage flow in dam sites, water inrush in coal mines and tunnels, and hydraulic fracturing engineering are usually induced by the accumulation of rock damage evolution (catastrophic) process. Whether our understanding and evaluation of these processes are correct or not depends on the in-depth study on rock deformation and failure process under water-rock coupling condition. The advances in rock seepage deformation-failure characteristics and relevant mechanism of the process, particularly the physical experimental results, are reviewed here. And the analysis models and corresponding numerical calculations for rock deformation, failure process under water-rock coupling are reviewed, especially the finite element method in view of the treatment of cracks. A number of representative research results achieved by the authors in recent years are briefly presented. Several specific challenges in the current theoretical (numerical) research and the prospects of future researches are then elucidated and suggested. |
