Built in the 1950s, the Moscow Luzhniki Stadium has recently undergone its third and largest reconstruction to become an elite category football stadium designed for use year-round. The project required reconstruction of the six-level, elliptically shaped structure while preserving the heritage façade and stadium roofing. Before beginning construction works, the team needed to address several geotechnical issues, including over-consolidated, Jurassic clay deposits, soil compaction, and existing utilities under the foundation slab.
They selected PLAXIS to model and simulate the impact of reconstruction activities, determining the optimal construction sequence in terms of soil deformation, stress, and stability. Using the 3D model increased reliability of the geotechnical forecast of the base displacements for the new construction and reconstruction of existing buildings and structures, providing opportunities to improve operational efficiencies in the final design. Bentley’s digital solution enabled more accurate predictions, improved construction reliability, and reduced the cost of the foundation through detailed soil analysis.
