Shao Chaoqun,Yang Dingying,Xu Linrong(School of Civil Engineering and Architecture,Central South University,Changsha 410075,China)  
To solve the problem of the prevention work of debris flow hazards,by using the fault tree analysis of systematic safety engineering,the main factors influencing the occurrence of debris flow hazards are found and the fault tree chart of debris flow hazards is established.The effect degree of each basic event on the occurrence of debris flow and the logical relation between them are analyzed from the three aspects of minimal cut set,minimal radius set and structural importance.Some suggestions are offered by combating with the key factors of prevention and the actual situation.The result has reference value and guidance significance to the prevention and the management of debris flow hazards.
