Influence Analysis of Ground Asymmetric Filling Load on Spandrel with Different Bases of Existing Open Trench Tunnels
Based on the theory of equivalent internal friction angle, the soil layers around the tunnel were equal to cohesionless homogeneous mass in this paper. On the basis of the Terzarghi unconsolidated mass theory, the local soil arching effect of the existing open trench tunnel which was located the side walls load was discussed under the ground asymmetric filling. Furthermore, when the backfill soil appeared the local soil arching effect, the critical embedded depth formula was given. Finally, it is concluded that both the size and distribution of the ground asymmetric filling load have influence on the local soil arching effect of the existing open trench tunnel.
