Analysis on vibration impact of the wing-room of Jiangxi Guildhall induced by the proposed Jinan Metro Line 6
To study the vibration impact of the wing-room of Jiangxi Guildhall caused by the proposed Jinan Metro Line 6,the measurements conducted on the vibration response of the wing-room under road traffic load by setting up six measuring points,and the numerical simulation of the wing-room vibration under the proposed subway operation conditions was carried out.The vibration response of the wing-room was comprehensively analyzed and evaluated by integrating the test data and the numerical simulation results.The impact of varying subway running speeds on the wing-room vibration was examined,aiming to provide a reference for taking appropriate vibration isolation to protect the integrity of ancient buildings.The results show that the maximum vibration response of the wing-room under the road traffic load reaches 0.068 mm/s,and the maximum vibration response under the subway load reached 0.09 mm/s,is located at the highest point of the south side of the wing-room.Both results meet the relevant regulations.However,considering the coupling effect of the road traffic load and the subway operation period,it is suggested to take the vibration isolation on the south side of the wing-room during the subway operation period.
