摘要
Abstract
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.关键词
