摘要
为了解拟建济南地铁6号线对江西会馆厢房的影响,对厢房设置6处测点进行交通荷载作用下振动响应测试,并进行了拟建地铁运行条件下厢房振动的数值模拟,结合实测数据和数值模拟结果对厢房的振动响应综合分析评估,为采取合理减振措施以保护古建筑安全提供参考.结果表明:路面交通荷载下厢房振动响应最大值达到了0.068 mm/s,厢房南侧最高处振动响应最大值达到了0.09 mm/s,均满足相关规定,但考虑地面交通荷载和地铁运行期间的耦合作用,地铁运行期建议对厢房南侧进行减隔振处理.
Abstract
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.
