Use of Borehole Shear Test to Obtain Shear Strength Data Comparison to Direct Shear Test

2018
The knowledge of shear strength geotechnical parameters, cohesion and friction angle, is necessary for many engineering works and slope stability analysis. Traditionally, the Direct Shear Test (DST) in the laboratory is used to determine these parameters.

Direct shear testing of seeds in bulk

Journal of Agricultural Engineering Research, 1980
Abstract To apply existing theories to the prediction of wall pressures in the structures for the storage of agricultural seeds it is necessary to know the shear properties of the materials to be stored. Equipment already used in soil engineering is unsuitable because of the lower stresses involved in testing seeds and the larger particle sizes.

Direct Shear Testing of Rockfill Material

Soil and Rock Behavior and Modeling, 2006
The shear strength of granular materials is mainly derived from the particle sliding friction and resistance resulting from reorientation and sample dilatancy. Parameters affecting the shear strength therefore depend on the relative density, gradation, particle strength, particle size and shape, and degree of saturation of the specimen. In this study a

Shear Strength of an Accumulation Soil from Direct Shear Test

Marine Georesources & Geotechnology, 2014
The present study focuses on the shear strength of the loose accumulation soil induced by the 2008 Sichuan earthquake. A series of direct shear box tests was performed to characterize the shear strength of the accumulation soil, under drained conditions.

The Improved Shear Strength Calculation Method in Direct Shear Test

Applied Mechanics and Materials, 2013
Direct shear test is broadly used to get the strength of soil, joints, and specific material in the field of geotechnical engineering because its simple structure and easier operation. But the current direct shear strength calculation does not concern on the variation of the shearing surface during the test, has no regard for the effects of the ...

A Direct Shear Test with Drainage Control

1953
Shearing strength data are presented as a function of intergranular pressure on the sample just before start of shear and maximum intergranular pressure in the past. Strengths by “controlled” direct shear tests, with prevention of change in sample thickness used to approximate a no-drainage condition during shear, are shown to be in reasonable ...

Numerical modelling of the direct shear test

Rudarsko-metalurški zbornik, 1995
Laboratory test results for the determination of shear strength on marly-limestone are presented. Apparatus AMP-1 was used, constructed for testing of medium size samples. These results were also used for numerical analyses with FLAC - finite difference code.
