Environmental assessment of soil conditions change over tunnels Rvangra Pvshshdar

This article examines the effects of soil liquefaction effects on tunnels and changing circumstances Pvshshdar Environmental deals. This study has tried to model Suitable for liquefaction behavior, forces of change and cover tunnel Balaamdgy Induced liquefaction is examined. For this purpose the FLAC software This type of modeling has the capability, is used. This article includes Two essential part is the first part introduces a reference model and the effects of liquefaction The soil model has been discussed. In the second part of the changing conditions Environment in the model, the forces created in the tunnel cover assessment Placed. The effect of various parameters on the change of forces Forms change and cover tunnel is being evaluated.
