摘要
将有限元强度折减法运用于隧道稳定分析中,建立某隧道有限元分析模型,综合考虑有限元计算不收敛、围岩塑形区贯通和特征点位移突变这三个判据。分析了公路隧道在有初期支护和无初期支护时的稳定安全系数。
As the strength reduction FEM is applied to tunnel stability analysis, a domestic single hole double highway tunnel finite element analysis model is establis - hed, comprehensive considering the following three criteria： the finite element calculation does not converge, plastic zone juncture and feature point displacement mutation criterion. Analyzing the safety factor of highway tunnel with and without initial support.
