| 摘 要： | 从斜坡地貌演化、地质结构和变形特征研究董家危岩体的成因机制及破坏模式。结果表明,其危岩体是下部基座蠕变和上部灰岩倾倒拉裂所致,以倾倒式破坏为主,也可发生滑移式和坠落式破坏。 |
| 关 键 词： | 危岩体 坡体结构 成因机制 破坏模式 |

| Abstract: | The formation mechanism and failure mode of the Dongjia dangerous rock-mass in Dayuan of Qingchuan County are studied from the topographic evolution,geological structure and deformation features of the slope.The dangerous rock-mass were resulted from the creep of the base and the topple-crack of the upper limestone and they present a failure of toppling mainly,possible sliding and falling. |
| Keywords: | dangerous rock-mass slope structure formation mechanism failure mode |
