Abstract：The influence of the side-pressure coefficient on the mechanical behaviour of tunnel linings is analysed. The analysis is based on the Austrian geotechnical software，FINAL，which considers the elasto-plastic behaviour of geomaterials，the function of bolts in tunnel and the stress release situation in tunnel excavation. The results show that the forces and displacements can vary in 15% while the side-pressure coefficient varies from 0.15 to 0.75.
