On the basis of the slice and gravity increase methods, a fundamental principle of couple analysis, and a procedure for calculating the slopesafetyfactor were put forward.
Different precipitation patterns and permeability coefficient of roadbed soil were analyzed by the calculation examples, the variation laws of changes of slopesafetyfactor was summarized.
