基于GIRAFFE软件的云南丽江大研古镇供水管网抗震可靠性评估

摘要

GIRAFFE是由美国康奈尔大学开发的一款非商业软件,也是目前世界范围内唯一一款广泛用于评估供水管网抗震可靠性的软件.鉴于国内学者对该软件的研究及应用尚未见报道,该文介绍了该软件的功能及优点、使用时应注意的问题与存在不足,这对相关研究的开展具有促进作用.丽江大研古镇是我国著名旅游景点且处于地震频发区,应用GIRAFFE软件评估了Ⅶ度、Ⅷ度地震烈度下大研古镇管网供水可靠性,其中包括7个社区、4个重要旅游景点及二所学校,所得结果对管网抗震设计、震后救灾工作开展具有一定指导意义.%GIRAFFE is a non-commercial software developed by Comell University,which is currently the only widely used software in the world scope for seismic reliability evaluation of water distribution system (WDS).Considering the research and application of the software of domestic scholars has not been reported,this study introduces the advantages,the problems should pay attention to and shortcomings of the software,which plays a promoting role in the development of related research.Lijiang ancient town is famous tourist attractions in China and located in the earthquake prone region.The seismic reliability of WDS of Lijiang ancient town in 7 and 8 degree earthquake intensity is evaluated using GIRAFFE software,including 7 communities,4 of the most important tourist attractions and two schools,the evaluation results has certain guidance meaning for seismic design of WDS,disaster relief work after earthquake.
