Through comparative study of two different geo-models of Liangshuijing landslide

it concluded that Liangshuijing landslide is in fact a paleo-falling and sliding rock accumulation without forming a whole and continuous “sliding belt”

and the landslide is divided into two parts named as the main sliding part at middle-below and the towed part at the up in terms of the landslide structure and the accumulation sequences. Also

the deformation mechanism has been researched

coming out the conclusion that the landslide initial deformation is due to the coupling process of reservoir water softening

uplifting and the river bank slumping; while in the condition of the reservoir operation

the main influencing factor of the landslide stability is rain fall

especially storm and long-time rainfall. It is also concluded from stability study that from May 2009 the landslide has entered the state of creeping by a slow process of stress releasing. Furthermore

from the prediction analysis of stability and failure mode

there comes the results that in the condition of reservoir operation

by coupling of strong and long-time precipitation and reservoir triggered bank slumping

the surface part of the main sliding body will be sliding firstly(sliding model 1)

and the sliding of the whole landslide is also possible (sliding model 2).
