The limit equilibrium methods

recommended or prescribed compulsorily in many engineering codes at home and abroad

are used to evaluate rock landslide stability. Because of the localization of limit equilibrium

there are lots of inconsequence about them. Therefore

how to improve limit equilibrium methods is one of the most important tasks in geo-technical engineering. Considering obvious weak slip zone occurring within rock landslide

the authors bring forward the different slip zone analysis methods during the calculation of finite element

and present the method combining the finite element method with non-equilibrium push transmission method used often in engineering. The method applied is used to calculate Qiancaotuo landslide stability

whose result is compared to that of non-equilibrium push transmission method based on limit equilibrium theory of rigid body. The comparison indicates that the proposed method is reliable

and can be used direct in engineering.
