Modeling of Volumetric Response of Cemented Sand Under Cyclic Loading [PDF]

, 1995
This paper first describes cyclic tests which were conducted by Iwabuchi (1986) on both uncemented and cemented sands using a true triaxial apparatus. The paper then presents a thermodynamic or endochronic model which was used to predict the volumetric ...

Development and validation of three-way rigid true triaxial apparatus for soils

Yantu gongcheng xuebao
The intermediate principal stresses have a significant effect on the stress-strain behavior of soils. To describe the stress-strain behavior of soils more accurately, it is necessary to carry out true triaxial tests in the field of soil mechanics.

Prediction of rockburst based on experimental systems and artificial intelligence techniques [PDF]

, 2012
Rockburst is characterized by a violent explosion of a certain block causing a sudden rupture in the rock and is quite common in deep tunnels. It is critical to understand the phenomenon of rockburst, focusing on the patterns of occurrence so these ...

True triaxial testing of sandstones and shales [PDF]

, 2014
In this study deformational and failure properties of sandstones and shales have been evaluated through laboratory experiments under true triaxial stress conditions. The impacts of intermediate stress and water saturation were investigated.

Anisotropic characteristics and creep model for thin-layered rock under true triaxial compression

Journal of Rock Mechanics and Geotechnical Engineering
The failure phenomenon of thin-layered rock tunnels not only exhibits asymmetric spatial characteristics, but also significant time-dependent characteristics under high in-situ stress, which is attributed to the time-dependent fracture of thin-layered ...

True triaxial test and failure criterion of coal gangue concrete

Meitan xuebao
In view of the pollution caused by the large storage of coal gangue and the shortage of natural aggregate in concrete, using coal gangue as coarse aggregate is a reasonable way to solve the above problems.
