摘　　要：为了研究中国大陆城镇供水管网抗震性能的区域差异特征,基于供水统计年鉴提取了各城镇供水管网基础数据,从管网规模、管道类别构成等方面分区域进行了差异性分析。采用与可获取数据相匹配的供水管网地震破坏评估模型,分析了18个城市供水管网的抗震性能,分区域统计分析了造成区域供水管网抗震性能差异的原因,同时,初步探讨了当地设防烈度对供水管网抗震性能的影响,最后,给出了提升供水管网抗震能力的建议。In order to study the regional difference characteristics of the seismic performance of China＇s mainland ur- ban water supply pipeline network, the regional differences were analyzed according to the scale of pipeline net- work, pipeline category, etc. and based on the urban water supply pipeline network basic data extracted from water supply statistical yearbook. The seismic damage assessment model of the water supply pipeline network was estab- lished in accordance with the available data, the seismic performance of water supply pipeline network in 18 cities was analyzed and the reasons leading to seismic performance regional differences of water supply pipeline network were statistically analyzed for each region. In addition, the impact of the local fortification intensity on seismic ca- pacity of water supply pipeline network was preliminarily discussed. At last, the suggestions on improving the seis- mic capacity of water supply pipeline network are proposed.
