Seismic stability of reinforced-soil wall by pseudo-dynamic method
Determination of the internal stability of reinforced soil walls under earthquake conditions is an important part of seismic design. The horizontal method of slices is used for determining internal stability or for tieback analysis of the reinforced soil wall. A pseudo-dynamic method is adopted in the present analysis, which considers the effect of phase difference in both the shear and primary...
متن کاملFrom Passive Dynamic Walking to Passive Turning of Biped walker
Dynamically stable biped robots mimicking human locomotion have received significant attention over the last few decades. Formerly, the existence of stable periodic gaits for straight walking of passive biped walkers was well known and investigated as the notion of passive dynamic walking. This study is aimed to elaborate this notion in the case of three dimensional (3D) walking and extend it f...
متن کاملPassive , Nonlinear , Mechanical Structures for Seismic Attenuation
Gravitational wave detectors aim to detect strain perturbations of space-time on the order of 10−21–10−22 at frequencies between 1 Hz and a few kHz. This space-time strain, integrated over kilometer scale interferometers, will induce movements of suspended mirrors on the order of 10−18–10−19 m. Seismic motion in this frequency band varies between 10−6 m and 10−12 m. Required seismic attenuation...
متن کاملEfficient Computation of Passive Seismic Interferometry
SUMMARY Seismic interferometry is from a computationally point of view based on cross-correlating two signals. One application of seismic interferometry lies in passive seismics. In passive seismic recorders are placed on the surface of the earth and signals are continuously measured. In this abstract we investigated an efficient way of computing the cross-correlation, of a limited number of ou...
متن کاملNatural Fracture Characterization Using Passive Seismic Illumination
The presence of natural fractures in reservoir rock can significantly enhance gas production, especially in tight gas formations. Any general knowledge of the existence, location, orientation, spatial density, and connectivity of natural fractures, as well as general reservoir structure, that can be obtained prior to active seismic acquisition and drilling can be exploited to identify key areas...
