Abstract
随着城市轨道交通的大规模建设,列车运行所致振动对文物建筑影响受到格外关注.回顾近20余年来国内古建筑防轨道交通微振动研究的典型案例.鉴于目前国内一些城市在地铁线路规划、建设施工、环境影响评价等环节上对古建筑防交通微振动问题存在一些误区,分析阐述微振动控制在文物建筑保护中的地位,提出古建筑交通微振动控制应围绕不影响文物3个价值为核心思想,以古建筑及其构件承振能力为基础来划分微振动控制等级,并建议振动标准的制定应与文物日常修缮相结合.结合已有研究成果对比分析地铁振动与路面交通振动对古建筑的影响,建议实施轨道交通减振时应同时控制路面交通振动.
With the massive construction of the urban railway transit, the vibration effects on the historic buildings by moving trains have aroused a great deal of attention. In this paper, some typical case studies on historic buildings protection from the micro vibration induced by railway transit in the recent two decades have been reviewed. Nowadays in some cities, however, there are some misunderstandings concerning the protection of historic buildings against traffic-induced micro vibrations in the planning, construction and environmental influence evaluation for the new metro lines. Therefore, the significance of the micro vibration control in the historic buildings protection is analyzed. The three key values of historic buildings which should not be affected by the traffic-induced micro vibration are proposed. It is suggested that the classification of the vibration control should be based on the vibration bearing capacity of the building structures and the determination of the vibration limit should be combined with the repair of the historic buildings. Finally based on the existing researches, the comparison of vibration responses by different types of traffic source is done. It is suggested to control the road traffic induced vibrations to protection the historic buildings when taking measures on metro’s vibration reduction.
