Model of calculus of variation used for determination of sliding surface

Determination of sliding surface is a key question in analysis of slope stability.Taking soil slope as an example,model and analytic formula of the most dangerous sliding surface are developed according to variational principle.From this principle,the critical sliding surface of soil slope and corresponding safety coefficients are directly found without assumption of sliding surface and conducting subdividing.This method can specifically be used in conditions of unknown sliding surface.
