地铁运行对邻近建筑振动响应研究
Study on the vibration response of subway operation to adjacent buildings
摘要
Abstract
With the rapid development of urban rail transit,the adverse effect of vibration caused by subway train operation on adjacent buildings have garnered significant attention.In this paper,Jinan rail transit line M1(Line 6)was selected as a case study,and one office building near Daming Lake East Station was selected as the research object.The finite element models were established to systematically analyze the influence of factors such as the operation of subway train,and the distance between buildings and subway tunnels on structural vibration response.The results indicate that when the operation subway trains,the vibration in all three directions belongs of the structure are characterized as low frequency,and the vibration velocity does not exceed the limit value.When the two-way trains operations occur,the vibration velocity of the structure in the vertical tunnel direction and the vertical direction increases,whereas it decreases in the vibration velocity in the parallel tunnel direction.Based on the analysis data,it is recommended that the distance between the centerline of two tunnels and the building should be maintained above 4.5 m.In the view of safety point,appropriate vibration reduction and isolation measures can be adopted in the tunnel or soil during the design phase.The numerical analysis results can better reflect the vibration process generated by subway operation.关键词
