The evaluation of characteristics and analysis of stability using three-dimentional numerical simulation of Enziping 2~# landslide

Landslide is one of the most familiar geohazards types both national and international.Its formation and stability are influenced by many factors.Thereby,there are many mechanism types of deformation and destruction,such as creep-sliding and fracturing,bending and fracturing,and so on.But the deformation and destruction of different landslide types all have the definite representation.So, further study on the representative landslide will have very good use for reference to the landslide which has the similar cause of formation.Therefor,combined with Enziping 2~# landslide,which mechanism is sliding and fracturing and locates near by the dam of Baihetan hydropower station,and through the detailed investigation and analysis to the characteristics,such as configuration,substance formation,structures and deformation and destruction,and so on,the influencing factors are discussed and its qualitative stability is evaluated.Furthermaor,the stability and the approach level of deformation and destruction are deeply analysed to the typical landslide using the three-dementional finite element analysis method,the results are compared with the evaluation outcome using two-dimension limiting equilibrium analytical method.
