In February 2006, a disastrous rockslide-debris avalanche occurred in tropical mountain terrain, on Leyte Island, Central Philippines. Over 1100 people perished when the village of Guinsaugon was overwhelmed directly in the path of the landslide. The landslide was initiated by the failure of a 450 m high rock slope within the damage zone of the Philippine Fault where the rock mass consisted of ...

The lining structure of Tunnel Boring Machine (TBM) excavated tunnels is composed of series of precast Reinforced Concrete (RC) pieces which are called segment. At the present paper, a novel method is introduced for seismic retrofitting of segmental tunnels located at active fault zones in rock environment with case study of Amirkabir dam to Tehran water transfer tunnel (Karadj tunnel). The mai...

Geological forces shape the earth’s crust. Normal faults, for example, form when extensional forces pull blocks of rock apart along a plane, whereas reverse faults are formed by compressional forces. Geologists classify faults to retrace the forces that have acted on an area; however, normal and reverse faults often look similar. In this study we investigated whether viewing superficially simil...

Distributed sensor networks working in harsh environmental conditions can suffer from permanent or transient faults affecting the embedded electronics or the sensors. Fault Diagnosis Systems (FDSs) have been widely studied in the literature to detect, isolate, identify, and possibly accommodate faults. Recently introduced cognitive FDSs, which represents a novel generation of FDSs, are characte...

To understand the stability of coal and rock in areas normal faults disturbed by dynamic loads blasting, damage characteristics within a fault are investigated using similarity simulation tests. The mechanism for gas outbursts is analyzed theoretically, results indicate that maximum tensile stress vertical direction blasting hole normal-fault model 1.17 times no-fault model. propagation cracks ...
