摘　　要：以日本阪神大震灾中神户、芦屋和西宫三市的给排水管道的震害为主要研究对象,分析了震害的分布及与地质条件、地震烈度、地表加速度等因素的关系;对三个典型区域进行了网格细化,有关数据归纳整理后表明这些因素虽与管道震害有一定的联系,但并非是导致地震破坏的主要因素;提出了相邻地层间地震时的相对位移这一指标,有受灾程度不同区域选点用等价线性有限元进行了计算,结果显示震害较轻的区域,地层的相对位移也较小,而相对位移大的区域也是震害严重的区域,从而表明相对位移对给排水管道这一地下线形构造物震害的直接影响。Aiming at the damage to water supply and sewerage pipelines in Kobe, Ashiya and Nishinomiya during 1995 Hyogoken - Nambu earthquake, this paper discusses the influential factor of damage to pipelines such as geological condition, seismic intensity, ground acceleration and so on. Results show that although these factors influence the damage to some extent, they are not main and direct factors. Then relative displacement is proposed and FEM is used to analyze the relation between it and the damage. Results show that relative displacement is small where the damage is slight and damage is cevere where relative displacement is much bigger.
