中文摘要：

由于土体与建筑物之间是弱耦合，忽略土-结构之间相互作用，解决了隧道-土体-建筑物模型对建筑物振动一般只分析到20 Hz以下振动的问题。分析DTⅢ-2扣件、弹性支承块轨道结构及Vanguard扣件下室内振动结果，将数值模拟结果与实测结果进行对比，分析结果表明二者吻合较好。将实测VLzmax结果与GB/T 10070及DB31/740的限值进行比较，提出对于不同振动要求的地区应采取相应的作为减振措施的轨道结构。对不同轨道结构下多层住宅室内振动分析有助于轨道交通部门采取合理减振措施来降低室内振动带来的影响。

英文摘要：

Because the relationship of ground and structure is weakly coupling, the interaction between ground and structure can be neglected. The problem of tunnel-ground-structure modal can merely obtain the results of vibration frequency below 20 Hz was overcome. The ground-borne vibration was analyzed under DTⅢ-2 fasten-er, low vibration track and Vanguard fastener. Comparing the simulation results with the measured results, it can be find that the simulation results and measured results are consistent. By means of comparison of results of VLzmax and limit of the codes GB/T 10070 and DB31/740, suggestion was put forward that corresponding track structure should be adopted as vibration reduction measure in different vibration request regional. This study offers a refer-ence for subway transit department to make reasonable measurement to deduce the influence of ground-borne vi-bration in buildings.
