Abstract

In this paper, the stability of a shallow tunnel in an environment with the existence of boulders in a soft soil was studied. A case study of a near-surface subway line crossing heterogeneous alluviums of Tehran plain was carried out. The interaction of the soil environment with the boulders and the influence of the volume of boulders on the stability of the tunnel were investigated using 2D numerical modeling. Numerical modeling and field investigations show that the size and volume of boulders will affect the stability of shallow tunnels, and larger boulders may effectively increase the tunnel stability. Therefore, investigation of the stability of the shallow tunnel should include the effect of the volume of boulders.
