Plasticity, limit analysis, and limiting equilibrium
1994A system of surface and body forces applied to a body will cause changes in the stresses and strains within it. The changes in strain will usually be partly elastic and immediately recoverable, but may also result in part from irrecoverable plastic yield. As the forces increase, a growing part of the body may reach the limit of its shear strength. Once

Limit equilibrium analysis of embedded retaining walls
Géotechnique, 1996Embedded retaining walls are often designed on the basis of limit equilibrium stress distributions. Although this type of analysis has been used widely for many decades, there is considerable scope for confusion and disagreement concerning the values of soil strength and soil– wall friction which should be adopted, and the way in which a factor of ...

Generalized Limit Equilibrium Method for Slope Stability Analysis
Applied Mechanics and Materials, 2012On the basis of the limit equilibrium method and the physical significance of Coulomb’s yield criteria, extremum conditions of yield functions is established, which will be the fundamental equations for the limit analysis of soil mass. Once the stress equation along a sliding surface is available, the normal stress on the sliding surface can be ...

Comparison of Limit Equilibrium and Limit Analysis for Complex Slopes
Geo-Congress 2013, 2013Conventional slope stability analysis uses various Limit Equilibrium (LE) methods to determine the minimum factor of safety and its associated critical failure mechanism. These methods frequently assume that collapse will follow a particular assumed geometry, which are effective for simple geotechnical problems, yet may encounter difficulties when ...

Slope Stability Analysis of Elastic Limit Equilibrium Method
Applied Mechanics and Materials, 2013Based on finite element analysis software ANSYS, slope stability analysis is carried out by Elastic limiting equilibrium method proposed in this paper. A series of sliding surface of the slope can be assumed firstly, and then stress field along the sliding surface is analyzed as the slope is in elastic state.

Limit Equilibrium Conditions and Stability Analysis for Soils
2018This paper describes recent advances in geotechnical stability analysis that combine limit equilibrium analysis with finite element stress analysis to provide a factor of safety and the failure load. This method, known as the finite element limit equilibrium method, is used to propose and prove the necessary and sufficient conditions required for ...

Slope Stability Analysis Based on Limit Equilibrium and Numerical Analysis
Applied Mechanics and Materials, 2012Based on the background of a foundation pit slope of the tertiary strong weathered basalt(TSWB), a quantitative analysis of the slope stability is proposed by combination of the limit equilibrium and the numerical analysis. The analysis also considers the effects of the natural state and soaking state Then, as an example, an ultra-deep foundation pit ...

The Limitations of Equilibrium Analysis in Political Science
1982William Riker, in his essay on the scientific problems created by disequilibrium (1980a) and in his essay on the philosophical problems raised (forthcoming), has offered a serious challenge to positive political theorists. Our essay is intended to do two things. First, we argue that the prospects for a science of politics are, perhaps, not as dismal as

A Soil-Tool Model Based on Limit Equilibrium Analysis
Transactions of the ASAE, 1983ABSTRACT A mathematical model for predicting the behavior of narrow tillage tools in soils is based on a limit equilibrium analysis. Pertinent soil, tool and interface parameters influencing the tool performance have been identified and incorporated in the model. A comparison of predicted and experimental results is also included.

Shallow instabilities in weathered slopes. Limit equilibrium analysis
2011Shallow instabilities can develop in cut slopes as a result of progressive weathering from the slope face. This creates a layer, a few meters thick, with reduce strength with respect to the parent hard material. This kind of instabilities is often corrected by applying a pressure on the slope face by means of a mesh nailed to the surface. In this paper,
