基于Mohr-Coulomb准则和强度折减法边坡稳定性数值分析

Numerical analysis of tunnel slope stability based on Mohr-Coulomb criterion and strength subtraction method

结合某隧道现场实测地质参数和地貌状况,建立了边坡的三维数值模型,基于Mohr-Coulomb准则和强度折减法,分析了渗透力作用下隧道边坡稳定性,并根据数值计算和分析结果,提出了合理的边坡加固措施。

A numerical three-dimensional model is established by field data of geological parameters and landform. Based on Mohr-Coulomb criterion and strength subtraction method,stability of tunnel slope considering seepage is analyzed,according to the numerical calculation and analysis,proper reinforcement measures for the slope are proposed.
