| 中文摘要: |
| 皖南山区受自然条件和人类活动的共同影响，滑坡地质灾害多发，对当地居民生命财产安全造成了较大威胁。文章以皖南山区一处典型的土质滑坡为例，调查分析了该滑坡周边的地质条件和2019年以来的变形特征，进一步对其稳定性和成因机理进行了综合分析，研究结论认为：该滑坡为浅层牵引式中型土质滑坡，失稳的主导因素为人类工程活动对边坡开挖和农耕活动对坡面植被的破坏，主要诱发因素为持续强降雨，破坏模式为滑移—拉裂破坏。研究成果可为今后此类土质滑坡的管控和治理提供参考。 |

| Under the common influence of natural conditions and human activities, landslide geological disasters occur frequently in mountainous areas of southern Anhui province, which poses a great threat to the safety of local residents and property. Taking a typical soil landslide in the mountainous area of southern Anhui province as an example, this paper investigated and analyzed the geological conditions around the landslide and the deformation characteristics since 2019, and further conducted a comprehensive analysis of its stability and genetic mechanism. The research conclusion is as follows: The landslide is a shallow traction type medium soil landslide, the main factor of instability is the destruction of slope excavation by human engineering activities and the destruction of slope vegetation by farming activities, the main inducing factor is continuous heavy rainfall, and the failure mode is slip-pull fracture. The research results can provide reference for the control and treatment of such soil landslides in the future. |
