The presence of water has been confirmed to play an important role in affecting the failure
properties of underground surrounding rock when subjected to complicated stress …

The present paper proposes a whole-process constitutive model of rock mass under freeze-
thaw-fatigue based on the Drucker-Prager criterion and the Lemaitre strain equivalence …

Abstract Rock-encased-backfill (RB) structures are common in underground mining, for
example in the cut-and-fill and stoping methods. To understand the effects of cyclic …

In practical engineering, cyclic stress caused by underground excavation, blasting or
seismic waves leads to initial damage to rocks, and the high temperature caused by fire will …

In the water conservancy and hydropower projects, the infiltration of weakly acidic
groundwater has an essential effect on the permeability evolution of sandstones. Previous …

To investigate the macroscopic fatigue properties and the mesoscopic pore evolution
characteristics of salt rock under cyclic loading, fatigue tests under different upper-limit …

Basalts have a wide range of porosity and pore size. Understanding the spatial and
geometry characteristics of basalt pores is vital to studying their mechanical and physical …

To reproduce the nonlinear damage of sandstone under cyclic loading, a nonlinear parallel-
bonded stress corrosion (N-PSC) model is developed based on the linear parallel bond …

Rock pore structure, including porosity, pore size, and particle size, plays a crucial role in
determining rock mechanical properties. This study investigates the impact of pore structure …

The use of infrared radiation technology for monitoring rock stability and failure has been a
common practice. However, the presence of groundwater significantly compromises the …
