The movement distance of seismic-triggered landslide is one of the important assessment indexes for prevention and mitigation of landslides disaster

and it is not only controlled by landslide volume and drop

but also related to the topographical factor. Here the slope toe-type and turning-type landslides are analyzed and the influence of sliding volume V

drop

slope gradient and turning direction angle is studied on the maximum vertical movement distance H

transitional movement distance L

and transitional movement distance under the slope toe or after the turning . The results indicate that the apparent friction coefficient H/L of the turning-type landslide is jointly controlled by the gradient and turning direction

and less than that of slope toe-type landslide. The average value of of the toe-type landslide is equal to that of the turning landslide

showing that the influence of topography factor on the transitional movement distances of different types of landslides is similar. Analytical formulations for movement distances of the two types of landslide are developed with respect to the volume

drop and topographical factor of the slides. According to the formulations

it is found that the landslide volume affects trivially the maximum vertical movement distance H

showing the movement characteristics of the high slope-landslide; the drop is not the main factor influencing the horizontal distances under the slope toe or after the turning ; gradient significantly influences the movement distances

and of slope toe-type landslide; and turning direction angle is an important factor controlling the of turning-type landslide. These results can provide references for predicting landslide movement distance and controlling topographical factors

highlighting the importance of the slope gradient and the turning directional angle.
