distributed fiber optic sensing has become more popular in tunneling applications....This paper introduces a novel sensing and evaluation concept, which combines DFOS strain measurements and geodetic displacement readings for distributed shape assessment along curved structures, such as tunnel
The Riyadh Development Authority recently executed one of the largest metro projects within the GCC region. The Riyadh Metro has 85 stations and 6 lines, covering approximately 177 km in total. AP Sensing was chosen to monitor this very prestigious infrastructure
At the Semmering Base Tunnel, Austria, fiber-optic sensing is used at every construction location to monitor tunnel linings, shafts, reinforced earth structures and pipelines.
Governor Cuomo abandoned plans for a 15-month shutdown of the Canarsie Tunnel....The team consulted with Kenichi Soga, Berkeley professor of civil engineering and a leader in developing fiber optics to detect potential vulnerabilities in large-scale infrastructure projects.
