Research on the quantitative risk estimation method of road slope disaster ka

This paper presents the framework of calculating the risk curve for road slope failures due to rainfall. First, the fragility curve is calculated based on the data such as past records of failures, precipitation records and results of slope stability inspection. Then the risk, defined as the socio-economical damages and losses, is estimated in the form of a risk curve based on the data such as the estimated scale of failures and the amount of traffic. This quantitative risk estimation method could help road administrators to undertake the effective and efficient risk management. For the covering abstract see ITRD E135448.
