摘要
///In the paper, in order to analysis the roadbed stability of Benxi section of Shenyang to Dandong Railway Passenger Dedicated Line and provide the basis for railway construction, the probability integral method is used to prediction, and the finite element software ADINA is used. The three-dimensional model is established. Analysis the influence of residual deformation for railway and Simulation analysis for the state after the gob grouting. The research shows the roadbed is essentially steady, the surface movement and deformation changes uniformly and gradually, won’t appear collapse suddenly but above the goaf have appeared the stress concentration and plastic deformation, the surface movement will still influence the operation of railway passenger dedicated line, considering the residual mining, compound mining and traffic load of railway, that may also cause old gob activation, should take measures for reinforcement.
