在盾构法隧道中将衬砌周围由于盾尾空隙的闭合、注浆充填作用和盾构推进对周围地层的扰动等形成的特殊圈层概化为具有平均意义的等代层。根据实测地层位移资料，用位移反分析法可较准确地获取等代层的参数。采用ANSYS有限元程序中的优化设计模块反演地层参数，以期对盾构法隧道设计与施工有一定的借鉴意义。

With respect to the forming mechanism of soil displacementand construction features of the shield tunnel, the concept of equivalent circular zone is supposed. With the help of the measured displacements, the parameters of the equivalent circular zone can be obtained exactly. This paper uses ANSYS finite element method to deduct the parameters of the equivalent circular zone, which can provide reference for the designingand construction of shield tunnels.
