摘　　要：阐述了引起公共交通型自动扶梯非操纵逆转的主要原因；应用故障树分析法（FAT）对非操纵逆转进行定性分析，得到最小割集．最小径集：运用公式计算出基本事件的结构重要度．运用最小割集方法来制订防止公共交通型自动扶梯非操纵逆转故障发生的方案。The main cause of unintentional reversal of the direction of travel for public transport type escalator is explained. The fault tree analysis method（FTA） is applied to qualitatively analyze the unintentional reversal of the direction of travel, the minimum cut sets and the minimum path sets are given. The structure important degree of basic events is calculated with the formula, and the minimal cut sets method is applied to formulate plan to prevent faults of the unintentional reversal of the direction of travel for the public transport type escalator.
