- Abstract:
- The spatial distribution and type classification of super large landslides can provide the basis for research on the formation mechanism, disaster-causing mode and risk mitigation strategy of super large landslides in Shaanxi Province. For seeking the spatial distribution regular and reasonable type classification of super large landslides in Shaanxi province, the statistics and analysis for the number and distribution according to physiognomy, tectonic unit and structure type of slopes were made based on remote sensing interpretation, field survey and investigation. The statistics result indicates that according to the physiognomy, 44 super large landslides are along the margin of loess tablelands, 22 ones lie in the loess hill ridge areas, 6 ones are locate in the north of Qinling Mountains, and 6 ones scatter in the mountain areas with middle and low heights in the west of Hanzhong sinking basin;on the basis of the tectonic units, 72 ones lie in the Guanzhong sinking basin including the northern Qinling fault belt, where the active faults develop, and 6 ones are in the Hanzhong sinking basin; in the light of the structure types of slopes, 41 ones develop in the slopes with structure of loess-mudstone, as well as 11 ones in the slopes with structure of loess-bedrock and 9 ones in the slopes with structure of loess-red clay. It proves that the spatial distribution regular of super large landslides in Shaanxi Province was controlled by the active faults, physiognomy and the structure types of slopes; and that the types of super large landslides are different with distribution areas, so the types of super large landslides in Shaanxi were classified into six ones, including bedding landslide with loess-mudstone along the margin of Baoji loess tableland, inversion layer landslide with loess-red clay along the margin of Bailuyuan loess tableland in Baqiao, and interface landslide with loess-red clay.
