Geophysical Characterization of Shear Zone in Direct Shear Test
2011Shear behavior of granular soils largely affects the safety and stability of underground and earth structures. This study presents the characteristics of the shear zone in a direct shear test using shear wave and electric resistivity measurements. An innovative direct shear box made of transparent non-conductive acrylic material has been developed to ...

Direct Shear Testing of Rockfill Material
Soil and Rock Behavior and Modeling, 2006The 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 behaviour of a cement grout tested in the direct shear test
Construction and Building Materials, 2018Abstract Portland cement grouts are widely used in the mining industry to bond cable bolts with the surrounding rockmass. Numerous laboratory and field tests showed that bond failure of the cable/grout interface is the dominant failure mode. Previous research has found that shear behaviour of the grout along a pre-defined plane plays a significant ...

Sand-Nonwoven geotextile interfaces shear strength by direct shear and simple shear tests
Geomechanics and Engineering, 2015Soil-reinforcement interaction mechanism is an important issue in the design of geosynthetic reinforced soil structures. This mechanism depends on the soil properties, reinforcement characteristics and interaction between these two elements (soil and reinforcement).

Development of a New Direct Shear Testing Apparatus
Rock Mechanics and Rock Engineering, 2009Politecnico di Torino and G.D.S. Instruments Ltd, UK has developed an innovative servo controlled direct shear apparatus named High Pressure Back Pressure Shear Apparatus-HPBPSA. The apparatus allows direct shear tests to be performed under closely controlled conditions in terms of axial load and back pressure applied to the specimen.

Shear Strength of an Accumulation Soil from Direct Shear Test
Marine Georesources & Geotechnology, 2014The 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, 2013Direct 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 ...

Investigation of shear performance of UHPC by direct shear tests
Engineering Structures, 2019Abstract Ultra-high performance concrete (UHPC) has been applied widely in modern structure construction. The outstanding mechanical properties of UHPC not only enable strong yet slim structural designs but also highlight its potential in protective structural constructions against extreme loads.

Large Direct Shear Tests Performed with Fresh Ballast
2018This study evaluates the ballast shear strength from the testing of 20 specimens, performed in a very large direct shear box that has a shearing plane of 1 m by 1 m and can hold specimens with a thickness up to 80 cm. Tests comprise two different types of ballast (mylonitic and andesitic) and two different specimen preparation techniques (with and ...

Interface Direct Shear Testing of Unsaturated Soil
Geotechnical Testing Journal, 2007Abstract A commercially available direct shear apparatus was modified for testing unsaturated soil and interfaces between unsaturated soil and stainless steel. Major modifications include the addition of apparatus for suction-controlled testing using the axis translation method, and construction of shear boxes for testing unsaturated ...
