摘　　要：故障树分析是核电站概率安全评价的重要方法,该文在介绍利用蒙特卡罗方法进行故障树定量分析仿真建模原理后,根据故障树所表示的系统模型的特点,绘制了故障树定量分析的程序框图,并根据框图编写了MATLAB程序。通过实例开发运用,证实该方法的有效性和可操作性。同时,我们还发现运用该方法计算可靠性,可以观察到系统中的各底事件对整个系统的影响程度,这对核电设备的设计、维修和改造具有很大的指导意义。The reliability qualitative analysis of the fault tree is an important part of probability safety appraisal in the nuclear power system. The paper introduces the simulation principle of qualitative analysis of fault tree based on Monte - Carlo method. Then the computer program is written to realize the reliability qualitative analysis of fault tree with the MATLAB language. Finally we proves the applicability and maneuverability of this way. At the same time ,we can also find the influence of the basic event on the system which can direct the design, maintenance and reformation.
