The effect of freeze-thaw weathering cycles caused by diurnal and seasonal temperature
changes is a significant disadvantage in the stability of rock engineering in cold regions. To …

Abstract Nuclear Magnetic Resonance (NMR) imaging in combination with mechanical tests
are carried out to investigate the influence of chemical solutions on porosity change, micro …

Long-term hydrochemical corrosion leads to mineral dissolution, meso-structure change,
and further mechanical deterioration of rock. This paper studied the effects of pH= 1, 3, 5 HCl …

Acid fracturing is one of the eligible techniques for increasing productivity of hydrocarbon
reservoirs. Laboratory tests are performed on reservoir rock samples to improve …

Rock fracture toughness is a critical parameter for optimizing reservoir stimulation during
deep resource extraction. This index characterizes the in situ resistance of rocks to fracture …

Temperature and chemical corrosion can strongly affect the micro and macro physical–
mechanical properties of rocks. In order to study the effect of coupled thermal-chemical on …

The primary objective of this study is to experimentally study the effects of different curing
temperatures (25, 50 and 75° C) and pressures (5, 10 and 15 MPa) on the mechanical …

Taking the sandstone subjected to pH= 1 and 3 HCl solutions as the research object, a
dynamic chemical damage model was established based on mineral dissolution theory and …

In deep strata, there is a risk that geotechnical engineering is simultaneously subjected to
chemical corrosion and dynamic loading, which seriously affects the safety of engineering …

The vast majority of rock masses is anisotropic due to factors such as layering, unequal in-
situ stresses, joint sets, and discontinuities. Meanwhile, given the frequently asymmetric …
