摘　　要：运用事故树对滑绳事故进行安全分析,采用模糊算法求取基本事件的发生概率,进而求出了顶事件的发生概率和各基本事件的概率重要度。依据重要度排序,对于超载、衬垫或钢丝绳受污染以及初始速度3项概率重要度较大的基本事件,提出了进行安全化设计、加强监督检查和安装后备保护装置等3项安全保护措施以降低其发生概率。Used of fault tree analyzing rope sliding accident,adopted fuzzy algorithm to calculate the probabilities of basic events,then the probability of top event and the probability importance of basic events were calculated.According as the order of the importance,for the three basic events of the bigger probability importance as over loading,liner or wire rope being contaminated and velocity,came up with three safety measures to reduce the probabilities which are safety design,strengthening the supervision and inspection and reserve protection devices.
