Influential Factors on Slope Stability and Landslide Mobility
The 2008 Wenchuan earthquake caused severe damage by landslide along the Longmenshan thrust belt zone in southwest China. The authors investigated various influential factors on slope stability and landslide mobility based on 97 landslides in Wenchuan County and 46 long runout landslides in Wenchuan earthquake area, respectively. The results demonstrated that slope height, horizontal peak ground acceleration (PGA), and geological structure were more influential to slope stability than slope angle and rock type. After slope failure, slope height, rock type, field cross angle and landslide volume were the most important influential factors on landslide mobility, and followed by slope angle and horizontal PGA. Two empirical models were developed to estimate landslide volume and landslide mobility. Their validity had been verified by the satisfactory agreements between observations and predictions. Therefore, they could be useful in the Wenchuan earthquake area and areas with similar geological conditions.
