Abstract
"Because the displacement rate of ""very slow"" and ""extremely slow"" moving reactivated landslides in stiff clays and clay shales, is typically controlled by fluctuations in piezometric levels; the relations between rate of movement and piezometric levels and factor of safety (proportional to inverse of shear stress level) are investigated. For the landslides investigated in this study there appears to be a nonlinear (power) relationship between the rate of movement and the factor of safety of reactivated landslides. It is concluded that for an approximately 0.1 increase in factor of safety (10% increase) the rate of movements decrease by about 5 to 20-times. (Abstract shortened by UMI.)."
