基于FLAC3D对某双隧道地压及围岩破坏分析

摘要

In this paper,the author uses FLAC3D numerical simulation software to simulate the excavation process of tunnel,based on the various geological basis parameters of surrounding rock of a double tunnel from tunnel seismic prediction and according to the Mohr-Coulomb theorem.The conclusions are drawn regarding the stress,the displacement and the plastic deformation in the excavation process.%运用FLAC3D数值模拟软件,依据TSP隧道地震勘探法检测得到的某双隧道的地质条件和围岩各项参数,对开挖过程中的某双隧道进行模拟,从而得出在开挖阶段应力、位移和塑性的变化规律.
