以北京西部地区浅埋砂卵石盾构施工产生的振动对周边建（构）筑物的影响为背景，借助ABAQUS有限元软件，计算各楼层动力响应，分析各楼层振动时域与频域特点，对地表环境影响进行分析，结果表明：由于盾构掘进振动频带较宽，且以中高频为主，振动波通过结构物基础向上传播过程中，由于与结构一阶、二阶振型频率差异，使振动峰值和频率不断衰减，其中水平向衰减较为明显，振级变化规律并不明显，随着结构物层数增加，水平向和竖直向呈增加趋势。

Shallow sandy pebble in west Beijing area of shield construction vibrations caused by the engineering background of a nuisance and the interference problem, based on field measured to obtain input of vibration wave in the areas residents complaints seriously, with the aid of the finite element software ABAQUS, floors dynamic response calculation, analysis of the vibration characteristics of time domain and frequency domain, the floors environmental impact analysis on the surface. Results show that the vibration due to shield tunneling wide frequency band, and mainly in high frequency, vibration wave propagation through structure foundation up, due to the type and structure of first order and second order vibration frequency difference, the vibration peak and frequency attenuation, one level to the attenuation is more obvious, vibration level variation is not obvious, with the increase of structure layer, the horizontal and vertical to the increased.
