Abstract

Slipping displacement of landslide is one of the most important assessment indexes for prevention and mitigation of landslide disaster, which is not only controlled by landslide volume and drop but also related to the influence of topographical environment.On the basis of detailed field investigation and inventory for 51 seismic-induced landslides and 16 rainfall-induced landslides seated in Dujiangyan area, the correlation between six factors and horizontal slipping displacement of landslides are analyzed through mathematical statistic method, factors including depositional gradient of slope, ridge height difference before and after the earthquake, plane shape, volume, and average thickness of landslide mass and friction coefficient of slope surface. Afterwards, the influence of different factors on different types of landslides before and after Wenchuan earthquake are sort out, and the predictive formulas of slipping displacement due to different causes are built which may support the disaster mitigation in the future. The preliminary conclusions reveal that slipping displacements of seismic-induced landslides are mainly affected by landslide volume(lgV), depositional gradient of slope(α), plane shape(R) and ridge height difference before and after the earthquake(ΔH); while rainfall-induced landslides are mainly affected by ridge height difference before and after the earthquake(ΔH), landslide volume(lgV), depositional gradient of slope(α) and friction coefficient of slope surface(μ). After the Wenchuan earthquake, the factors affecting the sliding of rainfall-induced landslides are changing with a relatively low correlation with slipping displacement, showing that their influence are decreasing and only landslide volume(lgV) still stays a strong correlation.
