Therefore, three theorems for weight characteristics of staticallydeterminate and indeterminate structures are presented and proved, and the essentials of the problem are explained in this paper.

A new slope stability analysis method, explicitly satisfying all limiting-equilibrium equations, is presented. To make the problemstaticallydeterminate, the variational approach is used.
