Triaxial shear testing of polished slickensided surfaces [PDF]

Landslides, 2011
A series of consolidated-drained triaxial tests were performed on precut and polished clay specimens to measure their drained residual strength. Two soils were tested during this research program: Rancho Solano Clay and San Francisco Bay Mud. Specimens were tested using a specially modified triaxial compression device which was developed to minimize ...

A Triaxial-Measurement Shear-Test Device for Soft Biological Tissues

Journal of Biomechanical Engineering, 2000
A novel shear-test device for soft biological tissue, capable of applying simple shear deformations simultaneously in two orthogonal directions while measuring the resulting forces generated in three axes, is described. We validated the device using a synthetic gel, the properties of which were ascertained from independent tensile and rotational shear ...

On Comparing Simple Shear and Triaxial Test Results

Journal of Geotechnical Engineering, 1984
It is indisputable that nonuniformities of stresses and strains exist in soils tested not only in the simple shear apparatus (SSA) but in the triaxial apparatus as well. These nonuniformities alone cannot explain the differences observed from the results of soils tests in the SSA and the triaxial apparatus.

Sand Liquefaction in Triaxial and Simple Shear Tests

Journal of the Soil Mechanics and Foundations Division, 1971
Data from cyclic loading simple shear and triaxial tests indicate that the important variable controlling the incidence of liquefaction in a given number of cycles in a saturated sand at a particular void ratio is the initial effective stress ratio; the ratio of the peak alternating shear stress to the initial effective mean normal stress.

Heterogeneous Fracture Slip and Aseismic‐Seismic Transition in a Triaxial Injection Test

Geophysical Research Letters, 2020
Fault/fracture slip and seismicity caused by fluid injection are of major interest to subsurface science and engineering. However, some fundamental aspects of the temporal and spatial evolutions of induced seismicity remain unresolved.

Behavior of an MBT waste in monotonic triaxial shear tests

Waste Management, 2013
Legislation in some parts of the world now requires municipal solid waste (MSW) to be processed prior to landfilling to reduce its biodegradability and hence its polluting potential through leachate and fugitive emission of greenhouse gases. This pre-processing may be achieved through what is generically termed mechanical-biological-treatment (MBT ...

Cyclic Triaxial Test to Measure Strain-Dependent Shear Modulus of Unsaturated Sand

, 2017
Dynamic shear modulus plays an important role in the seismic assessment of geotechnical systems. Changes in the degree of water saturation influence dynamic soil properties because of the presence of matric suction.

Strength of Sands in Wedge Shear, Triaxial Shear, and Shear Box Tests

Geotechnical Testing Journal, 2007
Abstract Limited tests had indicated peak drained values of angle of internal friction Φ of gravelly sands measured in the cylindrical wedge shear test (cylwest) to be relatively closer to the Φ expected from plane strain tests than from triaxial tests.
