In this paper, the problem of a retaining wall under active translation mode is investigated numerically. To this end, a series of numerical models is conducted using the discrete element code, PFC2D. The backfill soil is simulated by an assembly of separate cohesionless circular particles. Backfill soil was prepared by pouring soil particles from a specific height under gravity force and givin...

Abstract: The design of retaining walls requires the complete knowledge of the earth pressure distribution behind the wall. Due to the complex soil-structure effect, the estimation of earth pressure is not an easy task; even in the static case. The problem becomes even more complex for the dynamic (i.e., seismic) analysis and design of retaining walls. Several earth pressure models have been de...

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 ...

Introduction: It is generally assumed that the abundances of the siderophile elements in the terrestrial planet’s mantle are the result of core formation. High pressure experimental metal–silicate partitioning data for Ni, Co, V, Cr, Nb, Mn and Mo etc. were used to investigate the geochemical consequences of a range of models for core formation on Earth and the most popular model is a “deep mag...

To optimize the use of water for agriculture, knowledge of the seepage of the channel is required. Although there are many empirical equations for estimating canal seepage, the coefficients of these equations are different from Iranian conditions and these equations vary in different areas. In this research, the ability of the SEEP model was studied to estimate the seepage from earth canals in ...

Evaluation of active earth pressure in seismic condition is one of the important problems of geotechnical earthquake engineering. In this study the static and seismic active earth pressure exerted by a homogeneous backfill behind a rigid retaining wall is evaluated using Horizontal Slice Method (HSM). Both cohesionless and cohesive soils are considered using c- soil in the formulation. The fai...
