Tunnel 3/89
Tunnel Magazine, Volume 3/89
The Santiago Metro network comprises five lines. The Linea 2 South extension included 2.5km dual track running tunnels and two stations with a maximum span of 16.2m. Further, an excavation of 60-65m2 running tunnel in combined top heading/bench with a subsequent invert excavation. Reinforcement consisted of lattice girders, welded wire fabric for initial lining and welded wire fabric for final shotcrete lining. Dr. Sauer and Partners assisted in the production of design criteria for the final design and produced finite element structural computations for the large station caverns.
The successful design and execution of any geotechnical engineering project requires a thorough understanding of the expected behaviour of the subsurface and appropriate simulation. Dr. Sauer & Partners provides numerous services in the field of Geotechnical Engineering.
