隧道不同断面形式的有限元计算分析

Finite Element Calculation Analysis for Different Cross-section Forms of Tunnel

文章基于有限元分析软件MIDAS GTS-NX,建立了直边墙施工模型(模型1)和曲边墙施工模型(模型2),对采用不同断面形式对隧道结构变形和受力的影响进行了模拟计算分析,提出了曲边墙是更为合理、安全及稳定的洞型,为隧道的设计及施工提供参考和依据。

Based on the finite element analysis software MIDAS GTS-NX, this article established the straight-wall construction model （model 1 ）and curved-wall construction model（model 2）, conducted the simulation calculation analysis for the effect of different section forms on tunnel structure deformation and forces,and proposed that the curved-wall is a more reasonable, safe and stable hole type, thereby providing the reference and basis for tunnel design and construction.
