Bai, Y. (author), Wu, Jiansong (author), Yuan, S. (author), Reniers, G.L.L.M.E. (author), Yang, M. (author), Cai, Jitao (author)As a kind of critical infrastructure of energy transportation, so-called ‘utility tunnels’ have been developed around the world. Hosting a natural gas pipeline inside the natural gas compartment of a utility tunnel facilitates its maintenance but also brings potential explosion concerns due to the confined space. Although some work focuses on...journal article 2022
