In the present paper, discrete element method (DEM) is used to study wave propagation phenomenon in granular soils. The effect of factors such as coefficient of friction, frequency, normal stiffness and soil gradation on the wave velocity is studied. Using the wall motion based on the sinusoidal function is the method of loading used in this simulation, through which the pressure wave is transf...

The problem of estimating the settlement of shallow foundations on granular soils is very complex and not yet entirely understood. The geotechnical literature has included many formulae that are based on several theoretical or experimental methods to obtain an accurate, or near-accurate, prediction of such settlement. However, these methods fail to achieve consistent success in relation to accu...

The problem of estimating the settlement of shallow foundations on granular soils is complex and not yet entirely understood. In the past, many empirical and theoretical methods have been developed for predicting the settlement of shallow foundations on granular soils; however, these methods are far from accurate and consistent. In recent times, artificial neural networks (ANNs) have been used ...

one of the important problems in earthquake geotechnical engineering is liquefaction phenomenon that happens in loose saturated granular soils. in this study, 11 boreholes from govanjik and dayalar area in downstream of sattarkhan dam collected and evaluated. results of research are showed that with assuming cementation in soils, liquefaction potential is weak to moderate than non-cemented cond...

This paper presents results from drained cyclic torsional shear tests on Toyoura sand and a residual soil under dry and saturated conditions. The relationships of shear strain,   z with shear stress,   z ; normalized shear stress, z z     / ; vertical strain, z  ; and equivalent shear modulus, Geq are compared. The investigation of granular decomposition with respect to its influence o...

The bearing capacity of a single pile in granular soil was analyzed piles under vertical loads in the study of the mechanism of shaft fiiction. The effect of the deformation modulus on the bearing capacity of the single pile in granular materials, and especially in sand, was examined. By using the FLAC program for the finite element analysis it was possible to predict quite accurately the load ...

Expansive soils are often encountered in many parts of the world, especially in arid and semi-arid fields. Such kind of soils, generally including active clay minerals in low water content, enlarge in volume by absorbing the water through the surface and cause a great harm to the light structures such as channel coating, roads and airports. The expansive soils were encountered on the path of Ap...

Shallow foundations in granular soils are designed such that the settlements are within tolerable limits. Schmertmann’s (1970) method is one of the most rational methods for computing settlements of footings in granular soils, and is commonly used world-wide. The method relies on a strain influence factor that varies with depth. Schmertmann et al. (1978) proposed separate strain influence facto...
