| 摘 要： | 斜坡稳定性分析是滑坡预测的重要工作.开展甘肃东部地区斜坡稳定性评价,将该区域划分为10km×10km网格单元,对每个单元内斜坡的坡高、坡角、岩土组构、降水、构造(地震、活动断裂)及坡体破坏程度进行量化并进行动态聚类计算,对每一单元斜坡稳定性进行统计分类,将甘肃东部地区划分为稳定区、较稳定区、不稳定区、极不稳定区四大类型区.最终评价结果与斜坡发育特征实地调查及航片解译分析吻合较好,历史上滑坡发育的天水、陇南等地区仍是当前斜坡不稳定的滑坡易发区.研究结果为防灾减灾提供翔实了的资料,也有助于地质灾害的防治.

| Abstract: | Gansu province is the most serious area with landslide disasters. The generation and distribution of landslides are controlled by topography,landform structure,geological construction,climate and earthquake condition etc. The influence extent and action of the factors mentioned above are different place to place. The evaluation of the slope stability is very important to forecast the landslide.Zonal slope stable evaluation was made with marking out some certain parts.Study field is divided to some parts,of ... |
