Strength-weakening effect and shear-tension failure mode transformation mechanism of rockburst for fine-grained granite under triaxial unloading compression

, 2020
The occurrence of rockburst is closely related to initial high stress state and excavation unloading effects. To investigate the effects of three-dimensional (3D) stress state and unloading rate on the rockburst mechanism, triaxial unloading compression ...

Triaxial Testing of Weak Rocks Including the Use of Triaxial Extension Tests

1988
The strength parameters of New Zealand Tertiary weak rocks are found to be intermediate between soil and rock. The nonlinear strength envelopes of these materials for the range of stresses encountered in engineering structures mean that the strength parameters cannot be adequately defined using standard triaxial compression tests.

Triaxial tests on crushed ice

Cold Regions Science and Technology, 1996
Abstract To investigate the strength and the deformation behaviour of crushed ice, triaxial tests were performed. Crushed ice is formed during ice-structure interaction by extensive damage of polycrystalline ice near the structure. The effects of the confining pressure and the rate of loading are studied.

Triaxial testing beyond yielding

2017
This paper is continuation of work published at ISOPE 2015, where capabilities of undrained triaxial testing were presented. Now, drained loading is emphasized, recovery of disturbed sand properties is observed.After liquefying or yielding, sand becomes disturbed: stiffness and resistance to liquefaction become compromised.

Development of a Portable Triaxial Testing Apparatus—Smart Triaxial

2013
Reported in this paper are the design concept and performance of a light-weight triaxial apparatus that is portable, being contained in carrying bags and is nicknamed Smart Triaxial. It works with power supplied through AC 100 V or DC 24 V. The apparatus consists of (1) triaxial chamber combined with a loading system, (2) piston pumps supplying cell ...

A True Triaxial Testing Cell

1988
Results of both drained and undrained triaxial tests performed with a true triaxial cell on both natural and artificial clays are presented and discussed. The true triaxial apparatus, which has been used for about 20 years, is fully described. The apparatus has recently been modified to improve the measurement of lateral deformations.
