Abstract: With the increasing density of landmark buildings, the subway construction process on the ground worried about the environmental protection is a growing problem can not be ignored. Shield tunneling technology successfully used in subway construction, how reasonable prediction and control of shield construction of the surface deformation as a new topic. In the basis of an extensive literature, summarized previous calculation method, the finite element method of shield tunnel deformation of three-dimensional finite element simulation, compared with the measured data are more satisfied with the results.
Key words: tunnel, ground deformation, three-dimensional finite element analysis

After the introduction of shield tunnel with a century of development, while significant development, but inevitably lead to formation of the disturbance caused by ground deformation and land subsidence, especially in the shield tunnel in soft soil particularly. Disturbance lead to soil disturbance led to the strength and modulus decrease will lead to a long consolidation and secondary consolidation settlement. Deformation over a range of local level, it will seriously endanger the adjacent buildings and the safety of underground pipeline network, causing a series of geotechnical problems. Thus, the construction of the shield around the formation mechanism of disturbance is significant.
摘要：随着地标建筑物密度与日俱增，在地铁建筑过程中对地表坏境的保护是一个越来越不能忽视的难题。盾构法隧道施工技术成功运用于地铁施工后，如何合理预测和控制盾构施工对地表变形的影响成为了一个新课题。在查阅大量文献的基础上，总结前人计算方法，利用有限元方法对盾构隧道进行了三维有限元的变形模拟分析，与实测数据相比较计算结果较为满意。

1.引言
盾构隧道施工技术经过了一百年的发展，虽然有了很大的发展，但不可避免引起地层的扰动，引起地层变形及地面沉降，特别是在软土盾构隧道中尤甚。扰动导致扰动导致土体强度和压缩模量降低将引起长时间的固结和次固结沉降。当地层变形超过一定范围时，将会严重危及临近建筑物和地下管线网的安全，引起一系列的岩土问题。由此可见，盾构施工对周围地层扰动机理的研究具有重要的意义。
