NUMERICAL SIMULATION OF ELASTIC-PLASTIC STATE OF ROCK MASS AROUND EXCAVATIONS

摘要：

In the article one approach to determination of geo-mechanical tasks,which take into account the rock deformation breed over the strength limit,is described. Approach is adapted to solve the task with a numerical method. Verification showed that results which are got at application of this approach are adequate an analytical decision and a results ofin-situ.
