Assessment of the risk arising from near-surface natural hazard is a crucial step in
safeguarding the security of the roads in karst areas. It helps authorities and other related …

Active seismic monitoring was used to detect and characterize crack initiation, crack
propagation and crack coalescence in pre-cracked rock specimens. Uniaxial compression …

Slope movements in clay deposits are spread all over the world and result from complex
deformation processes, including internal strains in the landslide body and slipping along …

Refraction seismics is a common geophysical application to investigate permafrost in alpine
studies. This study reviews the physical basis of the use of refractions seismics and …

Pre-existing discontinuities act as the primary source of damage initiation processes in rock
masses, and consequently govern their overall deformational behavior. As laboratory tests …

The role of bedrock fractures and rock mass strength is often considered a primary influence
on the efficiency of surface processes and the morphology of landscapes. Quantifying …

A fractal wave velocity evolution model of the water-bearing coal is constructed to explore
the relationship between the complex pore and fissure structure parameters of the water …

Many studies show that certain geophysical methods, such as seismic and electrical-
resistivity imaging, appear to be well adapted for investigating the internal structures of …

An analytical and experimental study on a longitudinal wave (P-wave) transmission normally
across a filled rock joint is presented in this paper. The dynamic property of the filling …

Ultrasound has a very broad application prospect in monitoring the wetting range of coal
seam water injection. In order to explore the evolution of P-wave velocity with parameters …
