Analysis of the Influence of Vibration in the Underground Section of Intercity Railway on Ancient Buildings
[Purposes]By analyzing and predicting the influence of vibration of underground section of in-tercity railway on the structural performance of historic buildings during operation period,the corre-sponding vibration reduction measures are proposed to provide reference for the long-term protection of historic buildings.[Methods]Taking the proposed Shenzhen-Huizhou Intercity Railway as the engineer-ing background,the vibration limits of historic buildings(Nianfuxian Hospital)were determined accord-ing to the current national standards,and the numerical simulation analysis was carried out according to the recommended model in the"Technical Specification for protection of historic buildings against man-made vibration"(GB/T 50452-2008).[Findings]The results show that the vibration influence on the ancient building during the line operation period is much lower than the limit requirement.[Conclu-sions]After taking a series of vibration mitigation measures,the adverse effects of intercity railway vibra-tion on historic buildings can be mitigated to a large extent.
