Bromhead ring shear test procedure

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1992
Abstract Existing test procedures and a proposed modification for the Bromhead ring shear apparatus were found to yield drained residual strengths higher than values back-calculated from field case histories. A new test procedure is presented that yields drained residual strengths that are in excellent agreement with field case histories.

High velocity ring shear tests on sand

Géotechnique, 1984
Ring shear tests on sand materials have been carried out to show whether there is a change in the behaviour of these materials at high shearing rates and normal stresses. This question is relevant to the problem of the mobility of large rock avalanches (stürzstroms), but is also of more general academic interest.

Transition of shear flow for granular materials in a numerical ring shear test

Granular Matter, 2020
The shear flow behaviors of granular materials exist widely in natural events. Ring shear tests based on the discrete element method were carried out to study the effects of shearing rate on the transition of quasi-static and slow flow phases of granular materials.

Investigation on shear behavior of soft interlayers by ring shear tests

Engineering Geology, 2019
Abstract Most soft interlayers tend to be key factors affecting rock slope stability due to their low strengths. A series of ring shear tests is conducted on reconstituted overconsolidated soft interlayers to investigate the influences of remolded water content and normal stress on shear behavior under drained conditions.

Comparison of Shear Behaviour of sandy soils by Ring-Shear Test with Conventional Shear Tests

1998
The relation of shear behaviour of dry Toyoura standard sand between the ring-shear test, triaxial compression test and two types of shear-box tests was compared. Test results shows that the peak internal friction angles from the ring-shear test fitted those from shear-box tests, while there was a certain difference from triaxial compression test. Then,

Shear Band Formation Observed in Ring Shear Tests on Sandy Soils

Journal of Geotechnical and Geoenvironmental Engineering - ASCE, 2010
Shear band formation is an important factor in understanding failures in soil. In this paper, shear localization and shear band formation and evolution are examined using ring shear tests performed on three sands prepared by air pluviation. A transparent outer confining ring was used to visualize formation and evolution of the entire shear band.

Sand–geotextile interface shear strength by torsional ring shear tests

Geotextiles and Geomembranes, 1998
Abstract The torsional ring shear apparatus was developed to evaluate the residual shear strength of soft soils. It has the advantage of allowing large displacement to take place while shearing. In using geotextiles for geotechnical engineering applications, the soil–geotextile interface shear strength is an important design parameter.

Shear zone structures and stress fluctuations in large ring shear tests

Engineering Geology, 2013
Abstract Large ring shear tests are carried out in order to investigate the naturally drained shear behavior of slip zone soils of three giant landslides in the Three Gorges Project area. Twenty-seven specimens are sheared at three shearing rates (0.1, 1 and 10 mm/s).

Experimental study on the shear behavior of loess and paleosol based on ring shear tests

Engineering Geology, 2019
Abstract Landslide hazards frequently occur in the Chinese Loess Plateau every year, causing devastating casualties, damage to engineering structures, and reduction in land resources. This work presents an experimental investigation of four samples retrieved from Jingyang in the southeast of the Chinese Loess Plateau, using ring shear tests and ...

Objective Oriented Multistage Ring Shear Test for Shear Strength of Landslide Soil

Journal of Geotechnical and Geoenvironmental Engineering, 2004
Ring shear tests were conducted on five samples of different nature with a modified Imperial College type ring shear machine. The three different testing methods used, (1) individual sample testing for each normal stress, (2) increasing load multistage ring shear test, and (3) reducing load multistage ring shear test, all showed similar effective ...
