高速铁路桥梁支座对周围建筑物的振动影响研究

Research on vibration impact of high-speed railway bridge bearings upon surrounding buildings

通过建立车-线-桥-场地土-临近建筑物仿真分析模型,得到高速铁路桥梁采用不同类型支座时附近建筑物的振动数据,重点研究了不同类型支座的减隔振效果。通过与城市区域振动控制标准比较,最后得到高铁桥梁经过城市不同区域内建筑时的支座选用参考。主要结论对相关工程实际具有一定的现实意义。

By establishing the simulation analysis model of vehicle-line-bridge-site-soil-adjacent buildings,the paper obtains the vibration data of the neighborhood building when the high-speed railway bridge adopts different bearings,and mainly studies the vibration reduction and isolation effects of different types of bearings.Through the comparison of vibration control standards in urban areas,it finally obtains the bearing selecting reference while the high-speed railway bridge passing through buildings in different regions,which will have certain meaning for relevant engineering practice.
