Study on types and deformation mechanism of landslide in the fault zone of eastern Liupanshan: Taking source district of Jinghe river as an example

The stratigraphic in the eastern Liupanshan is special and the structure like the fault and fold is developed. There are many bad geological disasters such as landslide and hidden danger disaster. Special geographical, structural locations and potential seismogenic background make the area have the possibility of large landslide. Based on the new round of map investigation and evaluation with special subject research of geological hazards in the eastern Liupanshan, large amounts of data were obtained in the fault zone of source district Jing River. Through statistical analysis, geological environmental conditions and landslide characteristics in the fault zone of eastern Liupanshan were analyzed. The landslides in the study area were classified into the red bed soft rock landslide, the fault impacted type, accumulation landslide and loess landslide .The formation mechanism of the landslide were also discussed and analyzed. It provide an important theoretical basis for the evaluation of geological hazard risk zoning, the comprehensive prevention and control countermeasures of geological hazards.
