Fractures and other nonwelded contacts are important mechanical and hydrological features
of rock masses. Their effects on seismic wave propagation can be modeled as a boundary …

Seismic measurements take many forms, and appear to have a universal role in the Earth
Sciences. They are the means for most easily and economically interpreting what lies …

The mechanical and hydraulic properties of many rock masses are affected significantly by
the additional mechanical compliance and fluid conductivity that result from joints, fractures …

Many rock structures include multiple, near‐parallel, planar discontinuities such as bedding
planes or joints. The effects of these nonwelded interfaces on seismic wave propagation are …

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 …

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 …

Fractured rocks often support open, biogeochemical systems that play important roles in the
production of oil and gas, in the maintenance of environmental quality and influence the …

Researches on rock dynamics related to a cavern development project for ammunition
storage in Singapore have been carried out. The researches include the study of dynamic …

An equivalent viscoelastic medium model is proposed for rock mass with parallel joints. A
concept of “virtual wave source (VWS)” is proposed to take into account the wave reflections …

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 …
