Experimental verification of the intrinsic strainburst proneness of various rock types
A portion of excess strain energy is converted into kinetic energy after the peak load in Class II rock. That is the intrinsic potential energy for...

Experimental and Numerical Studies of Velocity and Turbulence Intensities for Mid-Channel Bar
AbstractTurbulent phenomenon in braided rivers is much more complex compared to the straight and meandering rivers. The turbulent flow structure at...

Observing eddy dye patches induced by shear instabilities in the surf zone on a plane beach
The effects of surf zone eddy generated by alongshore currents on the deformation and transport of dye are still poorly understood, and related...

Effects of Loading Rate on Rockburst Proneness of Granite from Energy Storage and Surplus Perspectives
Rockburst is a kind of rock failure phenomenon during which the internal elastic strain energy of surrounding rock mass is released dynamically under...

On the Dynamic Fragmentation of Rock-Like Spheres: Insights into Fragment Distribution and Energy Partition
Fragmentation of blocks upon impact is commonly observed during rockfall events. Nevertheless, fragmentation is not properly taken into account in...

Weibel Instability and Deformation of an External Magnetic Field in the Region of Decay of a Strong Discontinuity in a Plasma with Hot Electrons
AbstractIn this paper, for a number of significantly different parameters of a localized plane layer of collisionless electron–proton plasma and an...

An experimental investigation on the failure behaviour of surrounding rock in the stress concentration area of deeply buried tunnels
To investigate the failure behaviour of the stress concentration areas of deeply buried hard rock tunnels, model tests under uniaxial and biaxial...

Dispersive Fluxes Within and Over a Real Urban Canopy: A Large-Eddy Simulation Study
Large-eddy simulations (LES) are conducted to study the transport of momentum and passive scalar within and over a real urban canopy in the City of...

Identical Acoustic Waveforms Found Between Different-Sized Outbursts: Implications for the Propagation Mechanism of Coal and Gas Outbursts
Every gigantic Coal and Gas Outburst begins as a tiny, localized coal failure. This point of failure leads to a rupture of the coal seam, resulting...

Evolution of micro-damage and degradation of macro-mechanical properties of sandstone due to thermal effects
Previous studies on thermal induced damage of rocks concentrated mainly on the analysis of macro-mechanical properties. This paper documents physical...

Heating and Water Transport Behavior of Sandstones Under Microwave Irradiation
Microwave treatment has become a promising method to improve the efficiency of mechanical excavators in hard rocks. This paper conducted microwave...

A review of rockburst prevention and control methods in tunnels: graded and classified prevention and control
Rockbursts, as a kind of dynamic disaster that exists in tunnels for a long time, are of incalculable harm, which may lead to huge human and economic...

Effect of earthquake-induced liquefaction of runout-path material on the movement of landslide
The Donghekou landslide triggered by the 2008 Wenchuan earthquake was a typical large-scale rapid and long runout landslide. The saturated deposit...

Fracture evolution during rockburst under true-triaxial loading using acoustic emission monitoring
This paper investigates the fracture evolution during rockbursts of granodiorite and basalt that appeared to be representatives of two different...
