Analysis on Causes of Public Security Incidents of Serious Water Pollution in Three Gorges Reservoir

This thesis adopts security system engineering methods to analyze the public security incidents of serious water pollution in Three Gorges Reservoir and draw a diagram of fault tree analysis which directly indicates every possible basic event and its logical relations leading to top incident.Through qualitative analysis of Fault Tree Analysis,the minimal cut sets,the minimal path sets and the order of the structure importance have been found,which demonstrates the possible ways of protecting public security incidents of serious water pollution.
