Shear behavior of bolt–grout interfaces under constant normal stiffness: Influence of grout strength and thickness

open access: yesDeep Underground Science and Engineering, EarlyView.
The effects of grout strength and thickness on the shear behavior of bolt–grout interfaces (BGI) under constant normal stiffness conditions are investigated. Shear strength, failure modes, and acoustic emission characteristics are examined. The findings reveal that grout strength exerts a significantly greater influence on BGI shear strength and ...

Tri‐axial compressive behavior of high‐water material for deep underground spaces

open access: yesDeep Underground Science and Engineering, EarlyView.
The relationship between the mechanical behavior and microstructures of the laterally confined high‐water material associated with water bleeding was established. Abstract Attributed to its superior water‐to‐solid ratio and quick setting time, the high‐water material is widely adopted in underground spaces as a cost‐effective and environmentally ...

Stability analysis of a compressed air energy storage cavern transformed from a horseshoe‐shaped roadway in an abandoned coal mine

open access: yesDeep Underground Science and Engineering, EarlyView.
Stability analysis of compressed air energy storage caverns transformed from horseshoe‐shapes roadways in an abandoned coal mine is carried out. Both initial damage areas and two cavern shapes are numerically simulated using a one‐way coupling iteration algorithm of an improved generalization α method.

Failure characteristics analysis of the inclined interlayer during water‐soluble cavity construction of underground salt caverns for large‐scale energy storage

open access: yesDeep Underground Science and Engineering, EarlyView.
In the process of water‐soluble cavern construction of salt cavern energy storage, since the interlayer does not dissolve in water easily, sudden collapse will cause engineering accidents such as bending and damage of the inner tube of the cavern.

A Macro‐Model for Simulating Gusset Plate Buckling in Buckling‐Restrained Braced Frame Buildings

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT 2D models, which are conventionally employed for the seismic performance assessment of buckling‐restrained braced frame (BRBF) buildings, are incapable of simulating the out‐of‐plane buckling of gusset plates. This study presents a novel 3D macro‐modelling approach capable of capturing the out‐of‐plane buckling of gusset plates in BRBFs.
