Triaxial Shear Tests on Pervious Gravelly Soils

Journal of the Soil Mechanics and Foundations Division, 1956
Tests to determine shear characteristics of free draining gravelly soils; relations between shear resistance and density, amount of gravel, gradation, maximum particle size, and particle shape; effect of testing speed on shear test data and effect of specimen size for any maximum particle size up to 3 in.

Triaxial test behaviour of silty sands treated with agar biopolymer

International Journal of Geotechnical Engineering, 2019
In the current research, the study of undrained behaviour of agar biopolymer treated natural silty sand obtained from Kalpetta, Kerala was done. An experimental investigation was carried out to study the undrained behaviour of silty sand and biopolymer ...

Comparative study of shear strength characteristics of dry cohesionless sands from triaxial, plane-strain and direct shear tests

Geomechanics and Geoengineering, 2019
Knowledge of strength properties and deformational behaviour of soils under different loading conditions is necessary in the analysis of most of the geotechnical engineering problems.

Effect of tire crumb and cement addition on triaxial shear behavior of sandy soils

, 2015
This paper presents a series of conventional undrained triaxial compression tests conducted to determine the effect of both tire crumbs and cement addition on Narli sand specimens. The tire crumb contents and cement contents were 3%, 7%, 15%; and 1%, 3%,

Laboratory triaxial test behavior of xanthan gum biopolymer-treated sands

, 2019
Gel-type biopolymers have recently been introduced as environmentally friendly soil binders and have shown substantial strengthening effects in laboratory experimental programs.

Study of dilatancy behaviors of calcareous soils in a triaxial test

Marine georesources & geotechnology, 2018
In this article, the dilatancy of calcareous soil is studied systematically based on triaxial consolidation drainage shear tests, and the difference in dilatancy between calcareous soil and siliceous soil is also investigated.

Effects of Shear Band Formation in Triaxial Extension Tests

Geotechnical Testing Journal, 1996
Abstract The stress-strain and strength behavior from conventional triaxial extension tests is usually erratic due to excessive influence of necking in the hardening regime followed by shear banding. Two techniques have been attempted to impede the onset and gross development of strain localization. These resulted in macroscopically more

Shear Stress and Pore Pressure in Triaxial Testing

Journal of the Soil Mechanics and Foundations Division, 1965
The effects of frictional end restraint in triaxial testing may be avoided by using lubricated loading platens or segmental specimens. Segmental specimens consist of a central segment sandwiched between end segments that are sealed in a latex film. Pore pressures are measured only in the rather uniformly stressed central zone. Using this technique, the

Shear Banding in True Triaxial Tests and Its Effect on Failure in Sand

Journal of Engineering Mechanics, 2001
The occurrence of failure, mechanisms that create failure, and soil behavior in the vicinity of failure have been investigated. One mechanism is smooth peak failure, in which the soil continues to behave as a continuum with uniform strains, and smooth peak failure is followed by strain softening.

Shear fracture energy of Stripa granite- results of controlled triaxial testing

Engineering Fracture Mechanics, 1990
Abstract We have performed controlled triaxial experiments on Stripa granite in a ‘nearly stiff’ environment. This means that, before the commencement of loading, an initial confining pressure was ‘locked’ in the pressurizing chamber of the triaxial vessel.
