This paper examines two numerical methods commonly used in shoring design, namely the beams on elastic foundation method using WALLAP and the finite element method (FEM) using PLAXIS. Numerous design parameters are also investigated to study the effects of the parametric variations on each method. The shoring model analyzed in this study is based on a deep excavation project in the Sydney central business district. One of the significant findings of this study was that the results obtained from both WALLAP and PLAXIS showed marginal numerical errors, which, in turn, need to be examined closely. Generally, the beams on elastic foundation method are more conservative than the FEM. In comparison with the FEM, the soil modulus has more significant effects than the shear strength parameters in the beams on elastic foundation method. Moreover, the resulting shear forces, bending moments, and lateral displacements of the shoring are less sensitive to the variation of the soil friction angle than the cohesion. The findings of this study can be taken into consideration by practicing civil engineers when designing appropriate shoring systems in urban areas. © ASCE 2014.
