Based on studying uncertainties of the water level for flood control, floodwater, wind waves and crest elevation, this paper applies the interval analysis theory to establish the model of overtopping risk of earth dam and gives the calculating methods of overtopping risk interval and threshold.

Application study on overtopping risk analysis for Guangxi Chengbihe reservoir by Integrate-FOSM method;

Based on fault tree and vague set theory, an model of evaluating criteria of dam risk, in order to improve deficiency of traditional assessment method, such as lack of fuzziness and flexibility, and to be used for making safety and reliability evaluation for complex systems, is put forward.

The dam risk management decision support system under disaster load is a complex,large-scale system and it requires a lot of professional with various backgrounds to participate in.

Research on Earth Dam Overtopping and Instability Fuzzy Risk Analysis;

Study on Earth Dam Overtopping and Instability Risk Analysis and Its Application;

In this paper,the risks of overtopping in the cases of heightening the water level of flood control of Chengbihe Reservoir in Guangxi during the whole flood seasons and different stages are studied using the risk analysis theory of earth dam overtopping.

The basic theories,methods and status of research concerning dam risk analysis are outlined in this paper.

The dam risk analysis technique established on the basis of the probability of dam failure and the estimation of loss of life and economic loss has been widely applied to dam risk management abroad in recent years.

In recent years dam risk analysis and management established on the basis of the probability of dam failure and the estimation of loss of life and economic loss has been an advanced technology to dam safety management.
