| Zusammenfassung |
| Numerical simulation of seismoacoustic
emission (SAE) associated with fracturing in zones of shear stress
concentration shows that SAE signals are polarized along the stress
direction. The proposed polarization methodology for monitoring of slope
stability makes use of three-component recording of the microseismic field
on a slope in order to pick the signals of slope processes by filtering
and polarization analysis. Slope activity is indicated by rather strong
roughly horizontal polarization of the respective portion of the field in
the direction of slope dip. The methodology was tested in microseismic
observations on a landslide slope in the Northern Tien-Shan (Kyrgyzstan). |
