Modelling of fluid injection into a frictional weakening dilatant fault

Brice Tanguy Alphonse Lecampion, Federico Ciardo

Understanding the mechanism of nucleation of dynamic rupture is an important issue in seismology. It is the key factor in determining the seismic potential of pre-existing faults under long-term loadings. Furthermore, the activation of Mode II fracture by ...

Analysis and estimation of gripper TBM performances in highly fractured and faulted rocks

Federica Sandrone, Jian Zhao, Erika Paltrinieri

This paper focuses on performance analysis of Tunnel Boring Machine (in particular gripper TBMs) in highly jointed rock masses and fault zones. In order to investigate possible relationships between these difficult excavation conditions and TBM performance ...

Probabilistic simulations of TBM Tunnelling in highly fractured and faulted rocks

Federica Sandrone, Jian Zhao, Jean-Paul Dudt, Erika Paltrinieri

Despite the potential excellent performance of TBMs in favourable ground conditions, the presence of fault zones or heavily jointed rocks represent important geological hazards encountered during tunnel excavation. The effects of these challenging environm ...

Acoustic monitoring of laboratory hydraulic fracture growth under stress and pore pressure

Brice Tanguy Alphonse Lecampion, Thomas Emmanuel Blum

Fluid-driven fracturing is used in a wide range of applications, including oil and gas extraction, geothermal energy recovery, and CO2 sequestration. In order to efficiently fracture the targeted rock formation, theoretical models provide estimates of the ...

The role of the stress regime on microseismicity induced by overpressure and cooling in geologic carbon storage

Victor Vilarrasa Riano

Fluid injection in deep geological formations usually induces microseismicity. In particular, industrial-scale injection of CO2 may induce a large number of microseismic events. Since CO2 is likely to reach the storage formation at a lower temperature than ...

G: Fracture energy, friction and dissipation in earthquakes

Marie Estelle Solange Violay

Recent estimates of fracture energy G (') in earthquakes show a power-law dependence with slip u which can be summarized as G (') ae u (a) where a is a positive real slightly larger than one. For cracks with sliding friction, fracture energy can be equated ...

An empirically-based steady-state friction law and implications for fault stability

Marie Estelle Solange Violay

Empirically based rate-and-state friction laws (RSFLs) have been proposed to model the dependence of friction forces with slip and time. The relevance of the RSFL for earthquake mechanics is that few constitutive parameters define critical conditions for f ...

Stability of thin reinforced concrete walls under cyclic loads: State-of-the-art and new experimental findings

Katrin Beyer, João Saraiva Esteves Pacheco de Almeida, Angelica Rosso

Damage to structural walls in the recent earthquakes in Chile (2010) and New Zealand (2011) demonstrated that modern reinforced concrete (RC) walls may not achieve the expected ductile response but could possibly be triggered by out-of-plane displacements ...

Impact of thermally induced stresses on fracture stability during geological storage of CO2

Lyesse Laloui, Victor Vilarrasa Riano

Geomechanical stability issues may arise due to induced thermal stresses because CO2 will generally reach the storage formation at a temperature lower than that of the reservoir. Cold injection will form a cold region around the injection well, which will ...
