Monitoring sediment buildup in underwater bridge tunnels with the help of high-energy muons
The Shanghai Outer Ring Tunnel runs across the Huangpu River, with areas covered by mucky soil and silty clay (top). The researchers placed a portable muon detector within the tunnel to monitor muon flux as a way to measure the sediment buildup (bottom). Credit: Khaw et al. Over 200 underwater bridge tunnels exist for vehicular […]
