| Abstract: | o solve the stability problem of a multi-layered soil slope with the method of the limiting equilibrium theory,the method of giving a slipping range is used,The given slipping range is cut by several lines,which are divided into many line segments.The intersection points are connected with general arcs.By repeating the same process a series of cambered surfaces are forms.Then whether every cambered surface is a probable slipping arc is determined,and the reliability index for probable arcs is calculated.The minimum reliability index(the maximum failure probability)of the slope can be obtained by comparing the values for all probable slipping arcs-The method used in this paper has surmounted the difficulty that the minimum reliability index(the maximum failure probability ) can not be found by using the methods of optimization or random sampling. |
