盾构区间下穿合武高铁桥涵结构影响分析

摘要

This article is based on interval shield Erqi Road, a project of Wuhan Rail Transit Line 3 ~ Xingye Road Station under wear Wu high speed railway bridge and culvert structure, high-speed rail line design speed of 250km/h, set aside 300Km/h and the above conditions. The FLAC3D and ANSYS finite element calculation software and 3D stratum-structure model of high iron operation process of shield construction simulation calculation were carried out, and according to the results of analysis of shield interval, it proposed technical requirements and suggestions on design and construction..%本文以武汉轨道交通3号线一期工程二七路～兴业路站盾构区间下穿合武高铁桥涵结构为例，利用FLAC3D、ANSYS有限元计算软件，采用三维地层—结构模型对高铁运营过程中的盾构施工进行了模拟计算，并根据分析结果对盾构区间提出设计和施工方面的技术要求和建议。
