| Abstract: | The stability-loss of the counter-inclined stratified rock slope is one of the most urgent problems in practical engineering. The catastrophic model with cusp point based on catastrophic theory is established according to the rock mass structural characteristic of the counter-inclined stratified rock slope and the geological model of the bulking-tearing deformation. The conditions and mechanism of sudden change of stability-loss are studied as well. The critical stability-loss deepness of an instability point is given by the model. The method of stability evaluation is established based on catastrophic theory. The engineering example analysis proves the effectiveness of this method in the counter-inclined stratified rock slope. |
| Keywords: | catastrophic theory bulking-tearing counter-inclined stratified rock slope stability evaluation |
