True Triaxial Piping Test Apparatus for Evaluation of Piping Potential in Earth Structures

, 2010
: Current methods available for testing the piping potential of soils in dams (pinhole test, hole erosion test, slot erosion test) are limited to cohesive soils that maintain an open hole within the sample.

General Response Of Kneading-compacted Unsaturated Silty Sand Under Drained And Undrained True Triaxial Testing

, 2006
A comprehensive series of 36 drained and 36 undrained true triaxial tests was accomplished to investigate the stress-strain-strength behaviour of kneading-compacted unsaturated silty sand (SP-SM) under multi-axial stress states.

Research on the Outburst–Rockburst Coupling Disaster Law Based on True Triaxial Unloading Tests

The coal and gas outburst and rockburst coupling disaster is becoming increasingly serious due to deep mining. To clarify the mechanism inducing the outburst–rockburst coupling disaster, a true triaxial single-sided unloading mechanical test was ...

Three-Dimensional Mechanical Behavior of Kaolin Clay with Controlled Microfabric Using True Triaxial Testing

, 2004
Clays in their natural state are mostly anisotropic because of their modes of deposition. Many boundary value problems in geotechnical engineering involve soil elements that are subjected to stress paths with varying relative magnitudes and orientation ...

Investigation of the True Triaxial Failure Mechanism for a Medium Strength Sandstone Report 3: Classic Triaxial testing result and model calibration

, 2017
This technical report was prepared following a request from SCT Operations Pty Ltd for a geomechanical study on a medium strength sandstone. This study investigated the behaviour of Hawkesbury sandstone under true triaxial stress conditions, including 15

True triaxial failure characteristics in rocks from granite to sandstone: experimental results and theoretical predictions – a review

, 2014
Mogi’s (1971) seminal article on a new testing machine for conducting true triaxial experiments in rock included the first set of test results showing that failure (in the form of s1, peak) is a function of not only s3, but also of s2.
