Abstract:

This paper show the results of numerical accounts based on using the limit element software in the condition of axial strain and elastic zone for getting the information of excavation the tunnel in soil zones. The aim of this paper is giving the effect of tunnel section surface slope, effect of loads on the earth settlement. This study showed that some times the effect of these points should be less than the normal condition about 30 percent but, these changes can be effective in some important conditions. Effect of section shape about 30 percent and loads about 100 percent take high the settlement of earth.
