A novel true triaxial test device with a high-temperature module for thermal-mechanical property characterization of hard rocks

European Journal of Environmental and Civil Engineering, 2022
Rock mechanical property testing under high-temperature true triaxial compression conditions is significantly important to understanding the stability of deep underground engineering rock masses where high temperature exists.

State space model of undrained triaxial test data for Bayesian identification of constitutive model parameters

Geotechnique, 2022
Soil constitutive model parameters can be identified from triaxial test data. The identification is frequently performed by fitting a constitutive model to triaxial test data from a purely statistical or probabilistic perspective based on an assumption ...

Study of dilatancy behaviors of calcareous soils in a triaxial test

Marine georesources & geotechnology, 2018
In this article, the dilatancy of calcareous soil is studied systematically based on triaxial consolidation drainage shear tests, and the difference in dilatancy between calcareous soil and siliceous soil is also investigated.

Triaxial Testing Methodology for Gassy Soils

Geotechnical Testing Journal, 2023
ABSTRACT Small amounts of gas occur in almost every sediment in marine or coastal environments. In past studies, a negative influence of gas on the mechanical properties of soil was associated with geohazard occurrence and dike safety in tide affected areas.

Triaxial Tests on Cataclasites

Rock Mechanics and Rock Engineering, 2014
The Semmering Base Tunnel, a major railway tunnel project in Austria with a length of around 27.3 km was to be constructed through significant fault zones. The geotechnical parameters of the cataclasites especially in combination with high ground water pressure were of high importance for the geotechnical tunnel design.

A new fractional-order model for time-dependent damage of rock under true triaxial stresses

International journal of damage mechanics, 2022
To reasonably describe the time-dependent characteristics of rock under true triaxial stresses and analyze the long-term stability of deep underground engineering, based on the understanding of time-dependent mechanical properties of rock under true ...

Cubical Triaxial Tests on Cohesionless Soil

Journal of the Soil Mechanics and Foundations Division, 1973
A new type of cubical triaxial apparatus was used for an investigation of the influence of the intermediate principle stress on the drained stress-strain and strength characteristics of sand. For the same value of the minor principle stress and increasing value of the intermediate principle stress, both dense and loose specimens showed increasing slope
