Study on the Level of Acceptable Risk Level of Geohazards
摘要
Abstract
Study on acceptable risk level of geohazards is one of important research contents in the geological disaster risk control. Its goal is to identify the impact on vulnerability through estimating geohazard risk value. The level of acceptable risk is used as the criterion for risk assessment to judge whether the risk value can be accepted or not. Through analysis of the relation between the data of deaths because of geohazard and the total population each year from 2001 to 2010, the upper limit of acceptable risk level as 10 /a (tolerable risk line) and the lower limit as 10 /a in China are given. Finally, the FN curve for the acceptable risk level in China is plotted.关键词
