Abstract

Risk analysis of individual landslide is a very important content in the field of landslide risk research. Liangfengdong landslide in Wufeng County, Hubei Province was taken as an example to study individual landslide risk. The seepage field and stability change in different rainfall return periods were firstly simulated by Geo-studio software. The vulnerability of building and indoor individual was analyzed by combining qualitative and quantitative analysis. Furthermore, the annual economic risk and individual risk were calculated quantitatively by using exceeding probability method.Finally, risk zoning of individual landslide was also done. The results show that the area of residence affected by landslide was located in extremely high risk zone.The research results could improve the analysis of individual landslide risk, and offer an important reference for the prevention of Liangfengdong landslide.

Key words

individual landslide / seepage field / vulnerability analysis / quantitative risk analysis / stability / Liangfengdong landslide
