摘　　要：该论文的目的是对当前的各类核电厂防火屏障有效性分析方法进行对比研究,为工程实践提供参考。文中对用于评估核电厂防火屏障耐火能力的等效火灾持续时间评估法(包括等效面积法、等效温度法)以及计算机模拟法分别进行了阐述,并利用这些方法对核电厂中两种比较典型的防火隔间(液压机组间和电气设备间)的防火屏障耐火能力进行了评估,通过比较各种方法的分析结果,对这些方法的优缺点及其在工程应用中的适用范围进行了评估,指出了在评估防火屏障有效性时应结合具体的情况,选取合适的方法开展评估,在实际工程应用中建议优先采用等效面积法对耐火极限进行估算,与此同时,还应尽可能地应用计算机模拟法,进行更现实的估算或进一步了解特定隔间的火灾特性,后续还应从法规、标准、规范以及方法等方面进一步完善数值评估法,推动数值评估法在国内核电厂防火设计中的使用。The analysis aims to research and compare different analysis methods for validity of fire barrier in nuclear power plants to provide reference for engineering application. The analysis method for validity of fire barrier in nuclear power plants is discussed including equivalent fire duration method （i. e. equal area method and equal temperature method） and computer simulation method. The fire barriers of two fire compartments （hydraulic machine compartment and electric equipment room） are analyzed by these methods. The advantages, disadvantages and scope of engineering application of these methods have been assessed according to the compare of the different evaluation results. The paper points out that the analysis method of ~alidity of fire barrier in nuclear power plant should be selected according to practical conditions. It suggests that the preferred method is equal area method in the actual engineering designand at the same time,the computer simulation method should also be applied as far as possible to achieve more practical results or more detail fire protection features of the compartment. In the future, the computer simulation method should be improved in the aspects of code, standard,guideline and methodology to push forward the application of the method in fire protection design for nuclear power plant.
