| 摘 要： | 针对地下结构传统的简化计算方法的不足，采用适应性较强的有限元法，对盾构隧道施工过程中的施工步骤、管片与土层接触面以及开挖过程中地应力释放等多方面进行了有限元模拟，并且利用同济曙光软件计算和分析了盾构施工对临近构筑物的影响以及地层的变化情况，从计算结果来看是较为满意的。能够为盾构隧道衬砌的设计和施工提供有益的参考。

| Abstract: | Considering tunnel construction steps, contact surface between segments and soil and stress releasing, 2D-FEM are put forward to simulate shield tunnel construction to cover the shortage of the traditional computational methods to understructures and to analyze the contribution of construction to tunnels environments with software of GeoFBA. The conclusion and methods in the paper can provide valuable preference for tunnel linings design and construction. |
