Experimental study of mechanical properties of highly-stressed rocks under true triaxial unloading conditions with different unloading directions

Shuiwen dizhi gongcheng dizhi
During the excavation process of deep rock masses, the surrounding rock stress field forms alternating zones of stress increase (loading zones) and stress decrease (unloading zones) near the excavation surface, which can easily trigger instability and ...

Railway ballast anisotropy testing via true triaxial apparatus [PDF]

Transportation Geotechnics, 2020
This paper aims to demonstrate the anisotropic behaviour of railway ballast via true-triaxial tests. To do so, a novel, large-scale, true-triaxial testing apparatus (GeoTT) is designed and constructed. It consists of six hydraulic actuators, designed to apply a distributed stress to large granular cubic test specimens with dimensions: 500 mm × 500 m ...

A New Look at Massive Clusters: weak lensing constraints on the triaxial dark matter halos of Abell 1689, Abell 1835, & Abell 2204

, 2008
Measuring the 3D distribution of mass on galaxy cluster scales is a crucial test of the LCDM model, providing constraints on the nature of dark matter. Recent work investigating mass distributions of individual galaxy clusters (e.g.

Galaxy Clusters: Oblate or Prolate? [PDF]

, 1999
It is now well known that a combined analysis of the Sunyaev-Zel'dovich (SZ) effect and the X-ray emission observations can be used to determine the angular diameter distance to galaxy clusters, from which the Hubble constant is derived.

Influences of True Triaxial Loading-Unloading Stress Paths on Mechanical Properties and Wave Velocity of Coal Samples subject to Risk of Rock Burst

Shock and Vibration, 2021
To study fracture evolution and peak stress in burst risk coal samples (BRCSs) under true triaxial loading and unloading conditions, experimental and numerical research was applied to BRCSs under true triaxial stress paths entailing “x-direction ...

A Three-Dimensional Constitutive Model for Rocks Based on a Strain-Dependent Elastic Modulus

Lithosphere, 2022
Our research group previously proposed a simple two-dimensional (2D) constitutive model for rocks to simulate not only the axial stress–axial strain relationship, but also the axial stress–lateral strain relationship, with few complicated equations ...
