摘要
滑坡的孕育、演变、发生是一个累进性变形破坏过程,开展滑坡变形的长期监测工作对滑坡稳定性评价、滑坡的预测预报及治理具有重要的工程意义。目前,滑坡变形监测多集中于坡体表部,很难系统获得反映滑坡稳定性的深部变形资料。本文以某溃屈型滑坡为例,初步分析了滑坡深表部变形的关系,为滑坡稳定性分析及变形破坏趋势预测提供了依据。
Prengancy,development and occurance of landslide are progressive failure process,so it is very important to carry out long-term deformation observation yn landslide's stability assessment,predication and selection of countermeasures.At present,most of deformation monitoring data are focused on surface deformation,and deep deformation which reflects the state of landslide is difficult to get systematicly.In this paper,the relation between deep deformation and surface deformation of landslide is preliminarily analysed by taking a bulking landslide sa an example.The results provide a methol to evaluate stability and forecast deformation-failure tendency of landslide by taking advantage of surface deformation.
