| 危岩崩塌是山区一种常见的地质灾害，深入了解危岩崩塌的影响因素与演化机制，对于危岩崩塌地质灾害的防治具有重要意义。本文以大巴山某危岩体为研究对象，通过野外踏勘调查地形地貌、岩石岩性和构造特征，运用赤平投影及理论计算公式，分析该危岩体的稳定性，基于分析结果提出合理的防治对策。崩塌区域危岩体在正常工况下为基本稳定状态，在暴雨工况下为不稳定状态，综合评价为不稳定状态。根据该崩塌规模、稳定性、危害对象、危害程度、周边环境和施工条件，建议选择“危岩清运 +锚索肋板墙 +主动防护网 +被动防护网 +监测”的工程措施进行综合治理。该研究可为类似危岩崩塌地质灾害防治提供理论支撑与技术支持。 |
| 英文摘要: |
| Hazardous rock collapse is a common geological disaster in mountainous areas. In-depthunderstanding of the influencing factors and evolution mechanism of hazardous rock collapse is of great significancefor the prevention and control of geological disasters caused by hazardous rock collapse. This paper takes a certaindangerous rock mass in the Daba Mountains as the research object，and investigates the topography，geomorphol. ogy，rock lithology and structural characteristics through field investigation；Then，by using the steric projection and theoretical calculation formulas，the stability of the dangerous rock mass is analyzed，and reasonable preven.tion and control countermeasures are proposed based on the analysis results. The dangerous rock mass in the col.lapse area is in a basically stable state under normal working conditions and an unstable state under heavy rainconditions. The comprehensive evaluation indicates that it is in an unstable state. Based on the scale，stability， affected objects，degree of harm，surrounding environment and construction conditions of the collapse，it is recom. mended to adopt the engineering measures of "hazardous rock removal + anchor cable rib plate wall + active protec. tion net + passive protection net + monitoring" for comprehensive management. This research can provide theoreti.cal and technical support for the prevention and control of similar geological disasters such as dangerous rock col-lapses. |
