Determinação experimental, para solos residuais saturados, da variação dos parâmetros de resistência com a deformação axial
A description of an experimental technique which makes use of the triaxial test apparatus known as the IDS test as developed by Schmertmann. This technique allows us to determine the components of shear strength of soils, according to new definitions. The shear strength at any deformation is …

Analysis of reinforced embankments and foundations overlying soft soils
The use of tensile reinforcement to increase the tensile strength and shear strength of soils has lead to many new applications of reinforced soil. The use of such reinforcing in embankments and foundations over weak soils is one of the most recent applications of this technology. The studies …

Comparison of direct shear and triaxial tests for measurement of shear strength of sand
To ascertain the shear strength parameters of soils for engineering purposes is fundamental to soil mechanics and basic for designing earth-bearing and earth-retaining structures. Direct shear and triaxial tests are the most popular laboratory methods to determine these parameters. The direct shear …

Effects of Temperature on Residual Shear Strength of Cohesive Soils
… thermo-mechanical soil responses, the effects of temperature on residual shear strength of soils are not well understood. Previous studies on temperature effects on residual shear strength show some contradictory findings that might be attributed to the sample's mineralogical composition and …

Evaluation of the laboratory resilient modulus test using a New Mexico subgrade soil
… are measured. By definition Mr is the ratio of the peak axial stress to the corresponding recoverable axial strain. Currently, there are two accepted laboratory testing protocols for determining Mr, namely AASHTO T 307 and NCHRP 1-28A. These two standards differ from one another in ways that …

Għadira sands as compared to normally consolidated deposits at Marsa (Ta’ Ċeppuna) : using static triaxial tests
… alluvial deposits are being presented. A series of nine undrained triaxial compression tests were performed on these soils, at three different confining pressures, ranging from 55 to 1200kPa for clean sands, and 200 to 800kPa for the alluvial deposits. The behaviour of clean sands was observed to …

Genetic influences on the nature and properties of basal melt out tills
… regime is described and the classifications of glacier types are outlined. The modes of acquisition and transportation of the debris in glaciers is considered and the deposition process briefly considered. The various systems of classification of unstratified and stratified drift are given …

Finite element study of geosynthetic encased stone columns in sensitive soft clay
Some normally consolidated soft soils manifest strength sensitivity, ie these soil manifest strain softening when shear in an undrained mode. These soils, referred to as sensitive soft soils, have the typical features of strain hardening in drained shearing and strain softening in undrained …
