Description	The paper presents results of FE simulations of the Heathrow Express trial tunnel in London clay. The influence of constitutive equations on numerical predictions is evaluated and compared with field observations. The equations include two traditional models (Mohr-Coulomb, Modified Cam-Clay) and four models of different complexity (isotropic and anisotropic nonlinear elasticity with perfect plasticity, combined isotropic and kinematic hardening plasticity, and hypoplasticity). Nonlinear elasticity and hypoplasticity with intergranular strains come close to the observed behaviour whereas other models give non–realistic predictions due to an unsatisfactory behaviour in the small strain region.
