What determines cavern shape? What factors do geotechnical engineers consider when planning an excavation? What can be done to ensure the long-term stability and safety of an excavated cavern deep underground?
Students will discover the answers to these questions (and more) as they work to excavate and reinforce their own deep underground cavern models.
This engineering design challenge will encourage team building, elicit problem-solving skills, and require critical thinking as students learn about the excavation of about 800,000 tons of rock to make room for massive detectors- 4,850 feet beneath the surface of the earth- for the Deep Underground Neutrino Experiment (DUNE) at the Sanford Underground Research facility.
