摘　　要：地铁以便捷高效的优势迅速占领城市内交通的主导地位,但其运营诱发的振动对沿线居民带来的影响不可忽视。为明确地铁振动对邻近建筑物影响带来的不利影响,针对现阶段地铁振动评价标准的不统一,分析了地铁振动的有关理论与方法,综合大量文献研究了地铁运行引起的地面振动及其对邻近建筑结构的影响,研究可知地铁运行对建筑物振动影响与轨道的距离、建筑物层高及建筑材料等均相关。The subway quickly occupies the leading position of urban traffic with the advantage of convenience and efficiency,but the impact of its operation induced vibration on the residents along the line can not be ignored.In order to make clear the adverse effects of subway vibration on adjacent buildings,and in view of the different evaluation standards of subway vibration at present,this paper analyzes the relevant theories and methods of subway vibration,and studies the ground vibration caused by subway operation and its impact on adjacent building structures based on a large number of literatures.It can be seen from the research that the impact of subway operation on building vibration and the distance between the track and the building,building height and building materials are related.
