Abstract: Sensitivity analysis of influence factors on roadway deformation and lining axial force is conducted by using orthogonal numerical simulation experiment which has six factors (depth,lateral pressure coefficient,Young's modulus,Poisson's ratio,cohesion,internal angle of friction) with each factor having five levels.The results show that lateral pressure coefficient relative to lithology conditions is the most significant factor affecting the roadway deformation and lining axial force which increases rapidly with lateral pressure coefficient increasing.Roadway deformation and lining axial force exhibit the same trend for each parameter within a certain range of the swing,but the sensitivity of the various parameters for roadway deformation and lining axial force is difference.
