The Application of Quantitative Risk Assessment in Talus Slope Risk Analysis
Quantitative Risk Assessment (QRA) is a method of quantifying the degree of risk through a systematic examination of the factors contributing to slope stability and affecting the severity of the consequences, as well as the definition of probabilities for the individual factors. It has become an important tool for the management of landslide risk analysis and for planning risk mitigation measures. In this paper, QRA method is described in detail. There are multidisciplinary procedures for the quantitative risk analysis of talus slopes: hazard analysis, identification of the elements at risk, analysis of the vulnerability of the elements at risk and calculation of the risk. Basing on the method of QRA, the risk of talus landslides of Shuima freeway is analyzed in Yunnan province. Some risk mitigation measures are also suggested. Through the application, the merits and limitations of the QRA method are discussed.
