Fault Tree Analysis on Ship Drift Emergency of Three Georges Lock

This paper conducts the fault tree analysis on ship drift emergency of three Georges lock with the method of safety system engineering, draws a map of fault tree analysis, representing intuitively the basic events which can bring about top events as well as the logic relationships between them, obtains the minimum cut set, minimum path set and structure importance through qualitative analysis of fault tree, and points out the possible ways to prevent the occurrence of accidents.
