The Evaluation of Lithology Effects on Wenchuan Seismic Landslides
The landslides caused serious casualties and property losses in Wenchuan earthquake, China. According to the survey data of the landslides, the landslide lithology, contribution rate of lithology, height difference and volume of the landslides were studied. The results indicated that the 13 lithologies had the larger relationship with seismic landslide development. In these lithologies, The Phyllite (Ph) had the greatest contribution rate on the landslide number, landslide area and landslide volume. The Stone soil (Ss) had the largest volume of landslide on unit landslide area. Metamorphic sandstone (Ms), Gravelly soil (Gs), Sandstone (Sa), Phyllite (Ph), Limestone (Li) had the greater combined effects on the landslide development.
