  • The starting mechanism of earthquake-induced landslides was investigated in order to make a further research on the complex dynamics mechanism of landslide setting out. Based on the analysis of aggregated elastic strain energy, the expression of the setting-out velocity of seismic landslides was derived with the theory of energy conversion and by considering the vertical and horizontal accelerations of an earthquake together. The research result shows that the slope failure caused by earthquake is due to the comprehensive effect of "fluctuating oscillation chain", and seismic landslides go through a process from starting to accelerating to setting-out in the whole setting-out stage. The relative difference between calculated setting-out velocities based on the above expression and the momentum transfer method is about 3% to Donghekou landslide induced by the Wenchuan earthquake.
