Shallow translational slides are common in slopes during heavy rainfall. The classic model for the occurrence of translational slides in long slopes assumes rising saturation above a slip surface that reduces the frictional strength by decreasing the effective stress along soil discontinuities. The classic model for translational slope failure does not conform well to the nature of homogenous s...

Theoretical models for predicting penetration of non-driving (towed) rigid cylindrical wheels rolling on frictional/cohesive soils are presented. The models allow for investigating the influence of soil parameters and wheel geometry on the relationship between the inclined rolling force and wheel sinkage in the presence of permanently formed ruts. The rolling process is simulated numerically in...

Abstract This paper investigates the use of stability factors for estimating ultimate bearing pressures on cylindrical caissons in cohesive-frictional soils. Rigorous upper and lower bound limit analyses with finite elements axisymmetric (AX) condition are used a series numerical studies. The capacity ( N c 0 , q ? ) surface circular footing firstly revisited. is followed by study effect caisso...

This study extends the limit analysis techniques used for the computation of strict bounds of the load factors in solids to stability problems with interfaces, anchors and joints. The cases considered include the pull-out capacity of multibelled anchors and the stability of retaining walls for multiple conditions at the anchor/soil and wall/soil interfaces. Three types of wall supports are exam...

Within the context of immiscible biphasic flow in porous media, when nonwetting fluid invades pore spaces which are a priori saturated with wetting fluid, capillary forces dominate if network is formed by fine-grained soils. Owing to cohesion-less frictional behavior such soils, force–driven fracturing phenomenon has been put forward some researchers. Unlike purely mechanistic tensile mode-I th...

This paper presents an investigation on mechanism of the inclined 1 cone penetration test (CPT) using the numerical discrete element method (DEM). 2 A series of penetration tests with the penetrometer inclined at different angles 3 (i.e., 0°,15°, 30°, 45° and 60°) were numerically performed under µ=0.0 and 4 µ=0.5, where µ is the frictional coefficient between the penetrometer and the soil. 5 T...

some physical properties such as geometrical, gravimetrical, frictional and aerodynamic features of seeds of desi chickpea and its splits were studied at a moisture content of 8.2 and 9.0% w., respectively from north-western of iran. geometrical and gravimetrical properties including the average length, width, thickness, the geometric mean of diameter, sphericity, 1000-seed weight, unit weight,...

This research investigated the effects of types cohesive-frictional soil and geotextile reinforcement configurations on bearing capacity reinforced foundation (RSF) structures, via laboratory test numerical simulation. The four studied for RSF included: (i) horizontal planar form geotextile, (ii) full-wraparound ends (iii) with filled-in sand, (iv) sand backfill. soils were mixtures fine sodium...
