摘　　要：以重庆轨道交通六号线一期工程为背景,采用数值模拟方法,分析TBM施工引起的围岩振动效应特征。模拟结果表明,对一般的民用和工商业建筑,TBM施工振动强度在安全允许范围之内,但对振动敏感的结构,施工振动超出安全允许范围,需要采取减震隔振措施。Taking Chongqing Rail Transit Line 6 （Phase I ）as the background, the vibration effect of surrounding rock induced by TBM construction was analyzed by means of numerical simulation. The result shows that, for the general civil, industrial and commercial buildings, the vibration strength of TBM construction is within the range permitted; however, for the structures sensitive to the vibration, the strength is out of this range, and the vibration absorption and isolation measures are required.
