盾构施工条件下土体深层位移场分布规律的有限元分析

Finite Element Analysis of Distribution Regularity of Deep Displacement Field during Shield Tunnelling

结合上海轨交某线路工程实际,利用有限元分析方法,对盾构掘进引起的土体深层位移场分布规律进行了分析和探讨,研究结论可为今后类似工程施工提供参考。

Combined with one practical case of Shanghai rail transit line project,it introduces the distribution regularity of soil deep displacement field during shield tunneling.By finite element method,analysis is made to the deformation law of tunnel lateral soil.The study conclusion will be helpful for the construction of similar projects in the future.
