| 1. | The distribution characteristic of the crack face in rock mass was a important and difficult problem in mechanics of rock mass and engineering , the nature of crack face determined the transmogrification , stability , breakage laws and the seepage nature of rock mass directly , so the research had great value in theory and practicality
岩体裂缝面的分布形式是岩体力学与工程中重要和艰难的问题，裂缝面的形态直接决定了岩体的变形、稳定性及其破坏规律，决定了岩体的渗流规律，因此，这项研究具有很大的理论价值和实用价值。 |
