| Abstract: | The elastic plastic FEM model and rational calculation parameter were used to simulate and analyse the stress and displacement in the wall rock mass during different working stages of the double arch tunnel in this paper.The stress and displacement law of the supporting structure achieved and some beneficial results gained could offer the optimized working procedure to some double arch tunnel to direct working.Hence,great economic benefit could be attained. |
