摘要

Taking the stability analysis of Huocheling tunnel as example, the paper introduces the plastic-elastic mechanical analysis of surrounding rock stress-strain state, then explains the sensitivity of mechanical parameters (E, μ, C, Φ)influencing the surrounding rock stability according to FLAC3D numerical simulation software. It indicates that Elastic modulus E has the greatest affection on surrounding rock displacement; the shear parameters C, Φ also have great influences on stress redistribution; and the adjustments of μ and Φ influence the plastic area distribution and the surrounding rock stability directly. These conclusions not only provide the basis for surrounding rock stabilization but also provide guiding actions for the field construction.
