Study on the Acceptable and Tolerable Risk Criteria for Landslide Hazards in the Mainland of China
In recent years, demands for performing landslide quantitative risk assessments are increasing. Quantitative risk acceptance criteria must be established before performing quantitative risk assessment (QRA). Applying the results of such assessments is highly dependent on the definition of risk levels. Acceptance criteria applied in risk analysis are recapitulated. The current practice of authoritative acceptance criteria formulation is discussed from a decision theoretical point of view. Besides, some existing risk acceptance criteria applying the ALARP principle based on the established safety goals and quantification of these (containing the individual risk, economical risk, societal risk and environmental risk) are provided. The interim risk criteria are explained and their implementation is discussed. Finally a number of problems, such as whether the phenomenon of risk aversion of concern to the authority or to the owner, are discussed.
