Natural rock joint permeability deviates from the classic fluid flow governing equations due
to the inherent fracture surface roughness (ie, contact points, spatial correlation, matching …

Chemical corrosion of rock masses commonly exists in natural environment (eg, rock
masses immersed in acidic groundwater) and in rock engineering practice (eg, acid fluid …

Fluid flow in rock fractures is described by Darcy's law and its nonlinear extension, the
Forchheimer equation in form of a quadratic polynomial. Since the nonlinearity of the …

More than 240 experimental tests were conducted and the characteristics of real contact
area of the mated tensile fractures were investigated by using pressure-sensitive films. The …

The shear process can significantly affect the hydro-mechanical properties of rock fractures.
In the present study, a new approach is developed to predict the direct shear process of rock …

Rock hazards induced by shear slip along discontinuities are often encountered in deep
hard rock excavations. At present, grouted rebar bolts are still the most widely used …

Geological discontinuity (GD) plays a pivotal role in determining the catastrophic mechanical
failure of jointed rock masses. Accurate and efficient acquisition of GD networks is essential …

Direct measurement of the real contact area of rock joints under normal loading is crucial for
comprehending the subsurface geological processes. However, measuring this …

A proper understanding of the shear behaviour of rock joints and discontinuities is yet a
remaining challenge in the rock engineering research works owing to the difficulties in …

In order to investigate the effects of fracture surface roughness and initial stress on thermal
stresses generated in fractured rock masses, we conducted laboratory heating experiments …
