The mining and construction industries have long been faced with considerable attention
and criticism in regard to the effects of blasting. The generation of ground vibrations is one of …

The mechanical sciences are old and venerable. But age does not protect from stupidity.
The Cremona-plan and the theorem of the parallelogram of forces in their seniority have …

Stress waves propagating through multiple parallel fractures are attenuated (and slowed)
due to multiple wave reflections and transmissions at the fractures. This paper presents a …

In this study, the tomography of dynamic stress coefficient (TDSC) was established based on
a mechanical model of stress wave propagation in bedding planes and a mathematical …

This paper presents a theoretical study on normally incident elastic P-wave transmission
across single dry fractures with a nonlinear normal deformational behavior. The effects of …

When a wave propagates through fractured rock masses, it is greatly attenuated (and
slowed) due to the presence of fractures. In the situation where dynamic responses are …

The interaction between rock joints and blast waves is crucial in rock engineering when rock
mass is suffered from artificial or accidental explosions, bursts or weapon attacks. Based on …

Wave attenuation across fractured rock masses is a great concern of rock engineers to
assess the safety of underground structures in and on rocks under dynamic loads. Due to …

This paper presents an investigation of wave transmission in complex rock masses; the
rocks have different wave impedances on either side of a joint. The conventional …

岩体中存在着大量自然形成的节理, 这些节理导致岩体的力学性质, 振动, 渗透,
能量传递等多种性能发生改变. 爆炸应力波在含节理岩体中的传播与衰减也随着发生改变 …
