Tunneling in fault zones, Tuzla tunnel, Turkey

Tunnelling and Underground Space Technology, 2003
The Tuzla tunnel was excavated mainly in fault zones, shale and limestones using the conventional and shielded tunnel boring machine (TBM) methods. Fault zones in shales are brecciated and clayey, while those In limestones are of blocky structure.

Granular Packings and Fault Zones

Physical Review Letters, 2000
The failure of a two-dimensional packing of elastic grains is analyzed using a numerical model. The packing fails through formation of shear bands or faults. During failure there is a separation of the system into two grain-packing states. In a shear band, local "rotating bearings" are spontaneously formed.

Fault zones: A complex issue

Journal of Structural Geology, 2010
Faults are complex 4-D structures: volumes of complexly deformed rock that evolve in their structural and fluid flow properties through time.

Facies Modelling in Fault Zones

ECMOR X - 10th European Conference on the Mathematics of Oil Recovery, 2006
Traditionally fault impact on fluid flow is included by assigning transmissibility multipliers to flow simulation grid cell faces co-located with the fault plane (Manzocchi et al. 1999). A new method, called Fault Facies modelling (Tveranger et al. 2004, 2005), captures fault impact by considering faults as deformed rock volumes rather than simple ...

Fault Core/damage Zone; an Unhelpful Description of Fault Zone Structure?

Proceedings, 2012
The standard outcrop description of fault zones currently in vogue is a high strain fault core containing fault rock surrounded by a low strain halo termed a damage zone. This description does not acknowledge the significance of fault segmentation or displacement partitioning within fault zones and therefore fails to capture features which are crucial ...

Discontinuous fault zones

Journal of Structural Geology, 1987
Abstract Many tectonic faults and tension fractures are, at least initially, composed of separate segments. This note deals with a little explored reason for this phenomenon which, in faulting, has obvious implications both for the migration of hydrocarbons and for the sealing capacity of faults. Theoretical arguments based on CoulombMohr's theory of

Fault zone analysis: identifying motor defects using the rotor fault zone

Proceedings Electrical Insulation Conference and Electrical Manufacturing Expo, 2005., 2006
In the last decade, advancements in motor testing technology have brought forth advances in online and offline testing. Online current signature analysis (CSA) is quickly becoming a standard industry practice. Offline tests include advanced inductance measurements to analyze rotor and stator health.
