Central heating system have been rapidly developed in recent years.With the increase of heating demand,the length of urban underground heating pipeline(UUHP)was increasing repidly,accidents of heating pipeline underground happened sometimes.The safety of UUHP became an important problem of urban underground pipeline and also the key problem in urban development.From the angle of accident inducing issue,fault tree analysis was used to study the dangerous factors and feeble taches in the system of heating pipeline underground.Reasonable and effective preventive measures were discussed to effectively eliminate accident hidden trouble and reduce accidents,which is very important to ensure the safety of the heating network and the stabilization of heating in gear.
