摘　　要：本文借助模糊数学作为工具,以概率统计为基础,依据《室外给水排水和煤气热力工程抗震设计规范》(TJ-32-78)中直埋管道抗震验算理论和推荐的有关经验公式,提出了计算管道震害度并以择近原则预测管道破坏等级的方法;管网则按模糊图的有关原则结合网络分析理论,用λ截图法寻找管网的最安全路径,同时用择近原则确定网络的破坏等级。This paper presents a method of calculating the pipe damagegrades and the pipe damage class using fuzzy mathematics according to the earthquake resistance valuation theory of pipe and recommended experimental equations in 'Seismic Design Code of Outdoor Supply Water and Drainage, gas and thermal Engineering' (TJ-32-78). The safest path of the pipe network is found using λ cut graph method and the damage class of the network is estimated based on the network analysis.
