نویسندگان

چکیده

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 bentonite at replacement ratios 0, 20, 40, 60, 80, 100% by dry weight to have various values plasticity index (PI). analysis structures was performed using PLAXIS 2D software. Several factors studied, which embedment depth top layer (U), width (W), spacing between layers (H). Number (N) varied determine optimum parameters U/B, W/B, H/B, N, where B is footing width. most effective improvement technique found full wraparound outcome this will provide a preliminary guideline in design structure different ground other geosynthetic types.

Lateral Bearing Capacity of Piles in Cohesive Soils Based on Soils' Failure Strength Control

This paper presents the results of a series of numerical analysis carried out on piles in cohesive soils. Broms (1964a) proposed graphs to obtain ultimate lateral bearing capacity of such piles. However, the graphs do not cover all piles with different lengths. In this study, a finite difference program that is especially designed for piles is used. The investigations were carried out by varyin...

Numerical and Experimental Investigation of Yielding for Cohesive Dry Powder

We study the effect of particle cohesion on the steady state shear strength of a granular material. For cohesive powders, the steady state shear loci (termination loci) from DEM simulations are nonlinear with a peculiar pressure dependence due to the non-linear increase of contact adhesion with pressure in the contact model. Physical experiments are carried out on fine limestone powder in the d...

Experimental and Numerical Study of Tension Bearing Capacity of Circular Skirted Foundations Resting on Sand Bed

Skirted foundations are an appropriate alternative to deep foundations in onshore and offshore structures, which have the ability to withstand uplift loads, are also easy to be installed. The tensile performance of skirted foundations on sand was studied by physical and numerical modeling. Laboratory tests were carried out on small-scale foundation models with peripheral skirts. Numerical model...

Frictional Strain Hardening-softening in Experimental and Numerical Investigation of Arching Effect

In the current paper the results of a numerical simulation that were verified by a well instrumented experimental procedure for studying the arching effect over a trapdoor in sand is presented. To simulate this phenomenon with continuum mechanics, the experimental procedure is modeled in ABAQUS code using stress dependent hardening in elastic state and plastic strain dependent frictional harden...

An experimental and numerical study on the bearing capacity of circular and ring footings on rehabilitated sand slopes with geogrid

This paper presents the results of a series of small-scale model tests and numerical analyses conducted on circular and ring model footings located near geogrid reinforced sand slopes. Layers of geogrid were used as reinforcement. For numerical analyses Finite Element Method (FEM) was used. The effects of reinforcement depth, size, number of layers, and the horizontal distance between reinforce...
