A new approach is proposed to evaluate the non-limit active earth pressure in c–? soil based on horizontal slices method and limit equilibrium method, which takes into account arching effect, displacement, mobilized friction angle, tension cracks, shear stress of layer. The accuracy was demonstrated by comparing experimental results other theoretical methods. comparison showed that appropriate ...

Abstract One of the crucial factors that has gained widespread popularity during tunnelling construction process is face stability tunnel mainly depends upon support pressure to be applied at against overburden and surcharge loading acting on earth surface. In this study, different cross sections tunnels been investigated in cohesionless soil (loose medium dense sand) using Finite Element Analy...
