摘要
运用有限元分析软件MIDAS/GTS,构建了三维有限元数值模型,计算分析了不同间距条件下上跨新建隧道开挖对既有高铁隧道变形及受力影响,并探讨了两隧道的合理间距,从而保证隧道施工的顺利进行。
The paper adopts MIDAS/GTS,the finite element analysis software,establishes the three-dimension finite element model,calculates and analyzes the excavation of the newly-constructed overpass tunnel with various distances on the deformation and stress of the existing express railway tunnels,and explores the reasonable distance for the two tunnels,so as to ensure the smoothness of the tunnel construction.
