以北京地铁8号线二期盾构施工工程为研究背景，针对典型工况，首先利用盾构作业面现场测试，得到盾构施工振动振源的时程曲线，并分析其频幅特性；其次对盾构施工引起的建筑物的振动响应进行现场测试。在此基础上，利用Z_soil有限元分析软件，考虑隧道结构-周围土层-建筑物的动力相互作用，以实测振源时程作为荷载输入，建立盾构施工引起周围建筑物振动响应的三维动力有限元分析模型；结合现场测试的成果，分析地铁隧道盾构施工引起的周围建筑物的振动响应规律。主要结论如下： 1）盾构施工引起的横断面上的建筑物振动响应，随距隧道中心距离的增加而呈现出衰减的趋势，但又表现出一定的波动性； 2）振动对于作业面向前的建筑物的影响较其对于作业面向后的影响要大。

During the shield tunneling of Line 8 of Beijing Metro, the timedependent curve of the vibration source is obtained by means of field monitoring at the shield tunneling face and the property of the amplitude and the frequency of the vibration source is analyzed. Then, the vibration response of the surrounding buildings induced by shield tunneling is measured. 3D dynamic finite element model of the vibration response of the surrounding buildings induced by shield tunneling is established by means of Z_soil FEM program. The rules of the vibration response of the surrounding buildings induced by shield tunneling are analyzed on basis of the site monitoring results. Conclusions drawn are as follows: 1) The vibration response of buildings on the tunnel crosssection induced by shield tunneling would gradually decay as the distance to the tunnel center line increases, and it has fluctuation tendency; 2) The influence of the vibration on the buildings ahead of the working face is heavier than that on the buildings behind the working face.
