With the increasing in urbanization, tunnels became a necessity for major cities like Cairo and a large number of tunnel projects had to be undertaken worldwide. Tunnels are constructed to resolve transportation and sewerage problems and may pass near or under existing buildings. Conversely, constructing structures on top of existing tunnels could cause stresses increasing within the soil mass, which sequentially increase stresses transferred to and deformation of the tunnel lining. The interaction between the surface footings and underground tunnels depends upon several factors including the relative dimensions of the surface footings and tunnel as well as depth and eccentricity of the proposed tunnel. In this paper, a numerical investigation of a surface footing-soil-tunnel system is performed using the ABAQUS finite element code. To validate the numerical procedure and material constitutive models used in the present work, a comparison with relatively small scale experiments is first performed. The results obtained illustrate that an agreement between numerical and experimental results is reasonable. Further numerical investigations have been carried out for the different factors affecting the system response.

“…The mutual interaction between surface footings and tunnels could adversely affect their behaviours. Several investigations have been carried out numerically (see for example, Dessouki andMonforton, 1986 andDuddeck, 1987).

“…The bending moment was calculated after working out the pressure on the tunnel lining using the elliptical mode of failure. Dessouki and Monforton (1986) investigated the effect of soil failure on soil-steel structure systems by developing a plain strain finite element programme. It was found that numerical results were in good agreement with the experimental results of a model conduit.…”

Tunnels are constructed to resolve sewerage and transportation problems and may pass under or near existing buildings. Construction of shallow tunnels in urban areas can result in significant ground movement and could damage the function of civil engineering structures if care is not undertaken. On the other hand, building of structures above existing tunnels could lead to an increase in the stresses within the soil mass, which in turn could increase stresses transferred to and deformation of the tunnel lining. The interaction between the surface footings and underground tunnels depends upon several factors including the relative dimensions of the surface footings and tunnel as well as depth and eccentricity of the proposed tunnel. This paper presents the results of numerical and experimental investigations undertaken to explore the interaction between surface loading and underground tunnels. Experimental results indicated that the deformation of the tunnel lining is significantly influenced by the pressure exerted on the surface footings. A finite element code "ABAQUS" is utilised to simulate the interaction between a surface footing and an underground tunnel. Results of the numerical simulations seem along the lines of the experimental ones.
