摘　　要：研究了生命线工程系统抗震可靠度常规算法的适用性，定义了算法的时间复杂性和结构复杂性，分析了使可行算法失效的原因，给出了回路分解公式，提出了优先降低结构复杂性的简化原则。This paper researches the adaptation of conventional algorithm for seismic reliability of lifeline system, defines the time complexity and the structure complexity of the algorithm and gives the circuit decomposition formula on the basis of analyzing reasons making the algorithm invalid. At last, the paper presents the simplifying principle which regards reduction of the structure complexi- ty as the first importance.
