On this basis,a complete criteria for statistical control and or abnormality are proposed.

Deformation failure characters and instability criterion of abutment rock slope in Heihe reservoir

Discussion on analysis of slope instability criterion by strength reduction FEM

Analytical solution of instability criterion for fault rockburst is proposed using shear strain gradient plasticity theory and energy criterion.

In this paper, by the application of Ljapunov exponent, the conceptions of unstability criterion and stability degree are studied, and the relationship between the maximum Ljapunov exponent named LE 1 and the stability of slopes and also the physical concept of |LE 1| are analyzed.

An improved method about Loss stability criterion dealing some special instances is introduced afterthe insufficiency of the routine means is pointed out.

There are three failure criterias of shear strength reduction method using FEM.

There are three failure criteria of shear strength reduction method using FEM.

To resolve the numerous problems about stability analysis etc during the process of constructing expressways,the research on failure criteria of soil-similar cutting slopes was worked out by finite element method ANSYS in this paper based on shear strength reductionve methods.

A viewpoint that failure criterion should be matched with numerical calculation s iterative algorithm,strain mode assumption and other corresponding problems was put forward based on calculation and analysis of typical examples to study the applicability of different slope failure criterion in shear strength reduction finite element method(SSRFEM).

The safety coefficient has classified and in the meanwhile through the practice,a new failure criterion is proposed.

the method of rock simulation,the co-action of the dam and abutment,the mechanism of abutment instability,and the criterion of instability.
