Risk evaluation for Xiayahe landslide in Weibin District, Baoji City, Shaanxi Province, China

More Information
  • In order to research into quantitative risk assessment technique for multi-surface potential landslide, taking Xiayahe landslide which has four potential sliding surfaces in Weibin District, Baoji City, Shaanxi Province as an example, based on large scale(1:10000) field survey, geotechnical exploration, indoor analytic research and by using international single landslide risk calculation formula, fundamental characteristic and fatalness of Xiayahe landslide were briefly described and potential harmfulness, influence scope of every different potential sliding surface , time-spatial probability, vulnerability and risk were deeply researched. It’s also primarily evaluated that under different civil condition the overall risk of potential economic loss and death which leads to a quantitative expression. It’s indicated that Xiayahe landslide belongs to highly risky disaster-bearing body, compared to international risk tolerance standard., the risk value can′t be accepted, and certain risk mitigation measures must be carried on
