英文摘要The main aim of this paper is to define an elastic wave velocity threshold for rainfall-induced landslide prediction and early warning. To achieve this goal, several key questions need to be addressed, such as what threshold of wave velocity should be employed for issuing early warning? And how such thresholds should be selected? In an attempt to answer these questions, a total of 32 centrifuge experiments were conducted on model slopes. We first determined the critical deformation prior to initiation of shear failure. Then, the corresponding wave velocities at the critical deformation were compiled to establish a threshold of wave velocity to be used for early warning of landslides. Finally, a large-scale slope model test was performed to confirm the proposed threshold of elastic wave velocity. Based on the wave monitoring results, a warning is proposed to be issued at normalized elastic wave velocity of 0.9, and the slope toe is preferable for wave monitoring.
