摘　　要：雨污排水管道在城市排水中起到重要作用,而断层运动是引起管线破坏的重要原因之一,随着地下管线规模的不断扩大,管线安全事故也随之频繁发生,可能会对居民的人生安全、财产安全造成威胁,研究管道在受到地震时断层相对运动影响下的力学响应可对管道施工设计提供重要理论依据。对此,研究基于济宁任城区雨污分流工程,通过Midas GTS NX有限元分析软件建立断层与管道数值模型,分析地震力和断层面倾角对管道的影响。研究表明,该模型下的地震力与管道位移呈线性变化,断层面角度对管道变形的影响很小。研究成果可为雨污分流管道施工提供借鉴。Sewage and rainwater drainage pipelines play a crucial role in urban drainage systems.Fault movements are one of the primary causes of pipeline damage.As the scale of underground pipelines expands,the frequency of pipeline safety incidents has also increased,potentially posing threats to public safety and property.Studying the mechanical response of pipelines to fault relative motion during earthquakes provides important theoretical support for pipeline construction and design.Based on the sewage and rainwater separation project in Rencheng District,Jining,this research employs Midas GTS NX finite element analysis software to establish numerical models of faults and pipelines,analyzing the impact of seismic forces and fault dip angles on pipelines.The study reveals that under this model,seismic forces exhibit a linear relationship with pipeline displacement,and the influence of fault dip angle on pipeline deformation is minimal.The findings offer valuable references for the construction of sewage and rainwater separation pipelines.
