  3. Abstract:
  4. In this study, application of Limit Equilibrium (LE) and Finite Element Model (FEM) analyses have been presented and discussed for support design of a 30-m deep excavation in Tehran. A combination of nailing and strand anchorage with block system were designed and used to support the vertical cut in multiple steps of excavation. In this regard, safety factors have been assessed based on LEM using Mohr-Coulomb model, while deformations were estimated using the Hardening Soil model in an FEM platform. Comparison of the design models and field monitoring of deformations indicate a reasonably well performed engineering approach which can be implemented in similar projects in dense urban areas.
