地铁盾构下穿施工引起的既有线路轨道变形分析

摘要

Based on finite element software ABAQUS,a coupling model of down-traversing tunnel and high-speed railway structure was built to study the law of track settlement. The related conclusions can provide a reference for the construction and maintenance department works.%基于有限元软件ABAQUS建立了盾构隧道下穿施工—高速铁路结构间的相互作用模型，研究了盾构开挖过程中轨道沉降规律，相关结论可为施工单位和工务养护部门提供参考。
