Abstract:
On the base of the equilibrium of the whole force equilibrium of the slope, the whole moment equilibrium of the slope and the force equilibrium of the differential column, a general form of the three-dimensional limit equilibrium is calculated, and includes three equations. Through these equations and each assumption of the original methods, their analytic forms can be calculated. Thus, not only the computation quantities of the traditional method can be decreased greatly, but also the programming becomes very easy, and the computation efficiency also can be developed. At last, through the classical example and the analytic forms of the original methods, the effect of the sliding body width, the shearing strength parameters and the shearing force direction on the safety factor are analyzed. The result shows that the general form is valid.
