Reliability analysis to the stability of land slip based on the Swedish slice method;

Because of the concise concept and the simple formula,Swedish slice method becomes one of the most popular methods for stability analysis of landslides.

To study the effect of root system on slope stability,Swedish slice method was conducted.

Monte-Carlo reliability analysis of landslide based on numerical solution of Sweden slice method;

Sweden slice method, as a limit equilibrium method,is still extensively applied in the stable calculation of soil slope , but the phenomena of obscurity about the concept of stability coefficient and the origin of calculation formula often lead to misunderstanding and this affect the accuracy of calculation result of soil slope stability and its engineering design of protection and control.

Taking the Ⅶ area of the ditch as example,the paper checks the internal and out stability,it uses arc Sweden slice method in the check of internal entire stability,it has been proved by the checking results that the supporting method could assure safe of the excavation.

Research purposes: The accurate formula of the stability coefficient F_s and the circular parameters x_0、y_0、 r of a circular land-sliding surface have been obtained from the sweden circular slice method.
