Dynamic response of a rock fracture filled with viscoelastic materials
Wei Wu,Jianbo Zhu,Jian Zhao +2 more
TL;DR: In this article, a series of dynamic tests using a split Hopkinson rock bar was conducted on a simulated sand-filled fracture, and the experimental results showed that stress wave attenuation across the filled fracture is strongly affected by wave reflection and transmission at the fracture interfaces and the dynamic compaction of the filling sand.
Journal ArticleDOI
A study of the weathering of the bukit timah granite part a: Review, field observations and geophysical survey
TL;DR: The Bukit Timah granite exhibits a full range of weathering grades Examination of these exposures shows that the weathering has been rapid Field observations and geophysical surveys show that the rock has been weathered up to 70 meters depth as discussed by the authors.
Journal ArticleDOI
Obliquely incident wave propagation across rock joints with virtual wave source method
Jianbo Zhu,Jian Zhao +1 more
TL;DR: In this paper, Zhu et al. studied the wave propagation in a joint set with the virtual wave source method (VWSM) and derived the reflection and transmission coefficients across a single joint described by displacement discontinuity model.
Journal ArticleDOI
Role of filling materials in a P-wave interaction with a rock fracture
Wei Wu,Junxing Li,Jian Zhao +2 more
TL;DR: In this article, the role of filling materials (e.g., quartz sand and kaolin clay) in the interaction between a P-wave and a rock fracture is investigated, and the boundary conditions of the filled fracture, i.e., the displacement and stress discontinuities, are used in the method of characteristic lines to calculate the wave transmission coefficient in the time domain.
Journal ArticleDOI
Theoretical Methods for Wave Propagation across Jointed Rock Masses
TL;DR: In this article, the authors present a review and comparison of different theoretical methods for the analysis of wave propagation across jointed rock masses with the consideration of multiple wave reflections between joints.
