隧道运营期振动对临近建筑影响有限元分析

Finite element analysis of the impact of tunnel operation vibration on near buildings

铁路隧道下穿对振动、变形等有严格要求的建构筑物,应慎重考虑运营影响,以确保建筑物及铁路的安全。结合工程实际,通过数值模拟,研究铁路运营过程,临近建筑物振动及位移是否满足安全控制标准。根据有限元分析结果,对地面建筑的安全性进行评判。

In order to ensure the safety of buildings and railways,the impact of operation should be carefully considered when the railway tunnel underpasses the structures which have strict requirements on vibration,deformation and so on.Combining with engineering practice,through numerical simulation,this paper studies the railway operation process,whether the vibration and displacement of adjacent buildings meet the safety control standards.According to the results of finite element analysis,the safety of ground buildings is evaluated.
