双护盾TBM管片三维有限元计算分析

Three-dimensional finite element calculation of TBM segments with double shields

以国外某长引水隧洞为例,采用ANSYS软件,建立长引水隧洞三维有限元模型,分析六边形管片在欧洲标准下,不同工况、不同围岩类型的应力应变特征,对后续衬砌结构配筋及项目安全施工提供理论依据。

This paper takes a long diversion tunnel abroad as an example,uses ANSYS software to establish a three-dimensional finite element model,analyzes the stress-strain characteristics of hexagonal segments under different working conditions and different surrounding rock types under European standards,and provides a basis for subsequent lining structure reinforcement and project safety construction.
