Abstract:

Nowadays, the exiting methods of calculating the maximum horizontal distance of high-speed and long-distance landslides are not perfect. To further study the motion characteristics of high-speed and long-distance landslide, the geometry parameters about landslide were collected from the domestic and international literatures. Combining with the relativity and sensitivity theory, the relationship among the maximum horizontal moving distance, the maximum vertical height and the volume of the landslide is analyzed, and an empirical formula of maximum horizontal moving distance is obtained. The result shows that the maximum vertical height and volume of the landslide are positively correlated to the maximum horizontal moving distance, and the correlation coefficient of the maximum vertical height is the largest. The maximum horizontal moving distance is more sensitive to the variation of maximum vertical height, which is consistent with the correlation analysis results. The empirical formula of the maximum horizontal moving distance is put forward by considering the maximum vertical height and volume of landslide. The research results can be used for the analysis of the motion characteristics of high-speed and long-distance landslide to provide reference basis for the forecast and evaluation of disaster area and its intensity.
