Calculation of lateral earth pressure on retaining walls is one of the main issues in geotechnics. The upper and lower bound theorems of plasticity are used to analyze the stability of geotechnical structures include bearing capacity of foundations, lateral earth pressure on retaining walls and factor of safety of slopes. In this paper formulation of finite element limit analysis is introduced ...

The paper discusses the methods of erecting sunk wells and pile foundations, which consist in regulating frictional forces soils: lowering along lateral surface when sinking increasing foundations. developed method provides for application two types effective antifriction coatings surface: cutting edge structure above ledge. At same time, coefficients reducing friction by these various soils ha...

The bearing capacity of closely spaced footings has become one the important topics in geotechnical engineering research owing to rapid development urban areas around world. In this paper, we propose three efficiency factors that can be used describe effects using Terzaghi’s traditional equation. With an advanced finite-element limit analysis upper and lower bounds, both strip multiple on cohes...

Cohesive-frictional soils are widely used in the construction of embankment structures and due to the method of construction, i.e. applying compactive efforts in the vertical direction in these cases, the occurrence of anisotropy in the soil strength and permeability seems to be inevitable. In this study, attempts have been made to evaluate the shear strength of c-f soils through modifying a l...

The analysis of indentation of rigid cylindrical wheels into frictional/cohesive soils is presented. Threeand two-dimensional numerical simulations were performed using the finite element code ABAQUS to assess the influence of soil strength parameters, dilatancy, and wheel geometry on the relationship between the indentation force and wheel sinkage. The effect of three-dimensionality in the ind...

ABSTRACT: In this paper, shakedown limits of non-homogeneous soils in a half-space under rolling and sliding surface loads are investigated. The inhomogeneity of the soil is described by a power law for the variation of Young’s modulus with the depth. Mohr-Coulomb criterion is employed to characterise the cohesive-frictional behaviour of the soil. Analytical solutions to the elastic stress fiel...
