某坝区滑坡变形破坏特征及其稳定性预判

Distortion and Failure Character of a Landslide in a Dam Area and Its Stable Forecast

雅砻江中游某巨型滑坡距离拟选坝址仅1.3 km,目前滑坡体上有裂缝发育,滑坡的整体稳定性对于坝址的选择具有颠覆性的影响。因此,在概要介绍滑坡地质特征基础上,对滑坡体上裂缝发育分布特征及其成因机理探讨,对裂缝的产生是由整体还是由于局部导致给出明确回答,进而依据滑坡工程地质特征及定量计算对蓄水后滑坡的整体稳定性作出预测。

A giant landslide in the middle Yalong river which reaches the palnning dam only 1.2 km, at present there are cracks existence on the landslide body,and the whole stability of the landslide has the subversion influence to the planning dam site, Therefore,on the basis of the geological feature, researching the crack distribution characteristics and its causing mechanism, give a definite answer to the cause of the cracks which were caused by the partial or total. Then,based on geological features and calculating ,give a stable forecast to the landslide after storage of the reservoir.
