In this paper, triaxial compression tests on coals with real-time T 2 and MRI (Magnetic
Resonance Imaging) image measurement are performed by using a nuclear magnetic …

Under the action of a load, internal pores and cracks expand, and irreversible plastic
deformations occur. Compared with conventional rock mechanics tests, nuclear magnetic …

A knowledge of permeability evolution with stress is important for the enhancement of
coalbed methane production. In this study, a series of compaction-permeability tests with in …

It is very important to accurately calculate the frost heave force for the frost resistance design
of tunnels in cold regions. A computational model will divide the lining and surrounding rock …

Investigations of the flow and diffusion mechanism of grout slurry in underground fractured
rock mass are of critical significance to guarantee the grouting reinforcement of deep soft …

Investigating the damage degradation of rock during the freezing and thawing process is
more consistent with the actual engineering environment, considering its internal initial …

Rock masses in high-elevation or cold areas are vulnerable to the joint results of freeze-
thaw (FT) action and dynamic loading, it is thus significant to evaluate the tensile mechanical …

During the process of excavating underground space by artificial ground freezing (AGF),
moisture migration can aggravate the freeze-thaw destruction of the soil, which will lead to …

The coupling problem of freeze-thaw (FT) treatment and cyclic loading is extremely
prominent for rock engineering in Tibetan Plateau, which has triggered many serious …

Deformation and damage of the rock mass induced by excavation operations can result in
the tunnel wall convergence. Accurate prediction of the convergence is crucial for ensuring …
