论城市生命线工程系统的防(火)灾可靠度分析

On the Analysis of Reliability Taking Precautions against Fire Calamities for the Systems of City Lifeline Engineering

阐述了保证和提高城市生命线工程系统的防（火）灾可靠度的重要意义。引用了大量火灾及故障案例说明评估城市生命线工程内消防系统的可靠度是一项复杂的系统工程。介绍了当前在不同行业中采用的对复杂系统的可靠度进行评估的一些方法。在对这些评估方法进行比较后介绍了故障树分析法的优、缺点，并指出这种方法完全可以胜任对城市生命线工程系统的防（火）灾可靠度的分析工作。

This paper expounds the important meaning to guarantee and raise the reliability taking precautions against fire calamities for the system of city lifeline engineering.It quotes a large number of fire and fail cases to explain that it is a complex system engineering to evaluate the abiity of the fire systems in the city lifeline cngineering.It epresents some methods to evaluate the reliability of complex systems, these methods are being used in the different trades at the present. After comparing these evaluation methods, this paper presents the advantages and defects of analy tical method of the fail tree.It also shows clearly that this method can completely be competent at the job to analyze the reliability taking precautions against fire calamities for the city lifeline engi neering.
