摘　　要：为分析某档案馆建设及运行对邻近既有供水隧洞安全的影响,采用MIDAS GTS构建三维有限元模型进行分析,模拟了档案馆从施工到运行的全过程对邻近既有供水隧洞安全的影响。结果表明,项目施工及运行过程中,对既有供水隧洞在各方向上的位移量均小于规范允许值,满足安全要求。In order to analyze the influence of the construction and operation of an archive on the safety of the adjacent existing water supply tunnel,MIDAS GTS is used to construct a three-dimensional finite element model for analysis,and the influence of the whole process of the archive from construction to operation on the safety of the adjacent existing water supply tunnel is simulated.The results show that the displacement of the existing water supply tunnel in all directions during the construction and operation of the project is less than the allowable value in the code,which meets the safety requirements.
