FLOW OF WATER AND AIR IN SOILS DUE TO TUNNELLING UNDER COMPRESSED AIR

Nowadays tunnels in underground are driven by different methods. Moreover, tunneling in saturated soils requires control of groundwater. In some cases production of compressed air within the tunnel is an appropriate method to keep water out of the tunnel without disturbing the natural groundwater table and the surface too much; the rate of outflowing air also has to be calculated. Moreover, the flow of air and water affects calculation of the soil stability. Also, the classical empirical formulas include some confinements which are discussed in this paper. The description of the flow by field equations are also investigated critically. Finally, some ideas for description of flow of air and water in soils on the basis of the theory of porous media are shown.
