A further study on seismic response of a set of parallel rock fractures filled with viscoelastic materials

Jian Zhao, Wei Wu, Jianbo Zhu

The purpose of this study is to further investigate the seismic response of a set of parallel rock fractures filled with viscoelastic materials, following the work by Zhu et al. Dry quartz sands are used to represent the viscoelastic materials. The split H ...

Laboratory Investigation on Seismic Response of Rock Fractures Filled with Granular Materials

Wei Wu

Filling materials may exist in all scales of rock fractures, not only influencing seismic wave attenuation, but controlling rock mass instability. The objective of this study is to experimentally investigate the seismic response of rock fractures filled wi ...

Dynamic response of a rock fracture filled with viscoelastic materials

Jian Zhao, Wei Wu, Jianbo Zhu

Rock fractures filled with viscoelastic materials, such as sand, usually contribute to rock mass instability under the influence of seismic waves and dynamic loads. The purpose of this study is to verify that the specific fracture stiffness and the specifi ...

Seismic response of adjacent filled parallel rock fractures with dissimilar properties

Jian Zhao, Wei Wu

The purpose of this study is to analytically predict and to experimentally investigate the seismic response of adjacent filled parallel rock fractures with dissimilar properties (e.g., fracture thickness and stiffness). The time-domain recursive method is ...

Interface debonding driven by fluid injection in a cased and cemented wellbore: Modeling and experiments

Brice Tanguy Alphonse Lecampion

The integrity of the wellbore completion under injection conditions is vital for the effective, long term storage of carbon dioxide. Here we experimentally demonstrate and mathematically model fluid-driven debonding of the wellbore annulus in order to prov ...

Overview of Piano Key weir prototypes and scientific model investigations

Anton Schleiss, Michael Pfister, Marcelo Leite Ribeiro

The interest in Piano Key weirs (PKW) was increasing over the past years, both in terms of application and hydraulic research. Several systematic model test series were per-formed and published so far, originating from different hydraulic laboratories arou ...

Self-Sealing of Localised Cracks in Boom and Opalinus Clay Hollow Cylinders

Laurent Gastaldo, Vincent Labiouse, Jean-François Mathier

The SELFRAC project aimed to study the fractures within the Excavation Damaged Zone (EDZ) around galleries in the Boom clay and Opalinus clay formations and their possible sealing/healing with time. Tests carried out at LMR-EPFL aimed at quantifying on the ...

Scratching as a Fracture Process: From Butter to Steel

Pedro Miguel Nunes Pereira de Almeida Reis

We present results of a hybrid experimental and theoretical investigation of the fracture scaling in scratch tests and show that scratching is a fracture dominated process. Validated for paraffin wax, cement paste, Jurassic limestone and steel, we derive a ...
