翻身沟泥石流危险度评价及防治研究

根据地质勘察资料,论述了翻身沟泥石流地质灾害基本特征、发生机理、规模及发展趋势,并通过多因素危险度评价公式对翻身沟泥石流危险度进行评价,得出翻身沟泥石流危险度为0.51,属中度危险的泥石流沟。针对灾害体物源储量、破坏能力等基本特征,以及危险区周边地物、地质结构特征,提出了以拦为主辅以沟道清淤的综合防治措施,以保证翻身沟居民、省道等生命财产安全。

Hazard Assessment and Countermeasure of Debris Flow in Fanshen Gully

According to geological survey data，the paper discussed the basic characteristics，the occurring mechanism，the scale and development trend of debris flow in Fanshen GullyIn addition，through evaluating the hazard degree of Fanshen Gully with a multi-factor hazard assessment formula，it is concluded that this debris flow risk degree is 0.51，belonging to the moderate risk of debris flow gulliesIn view of existing resources and destructive ability of disaster，as well as the surface features，geological structural features around danger zone，a comprehensive prevention and control measure with blocking as main and dredging as auxiliary is proposed to ensure the safety of residents，provincial roads and other life properties in Fanshen Gully
