Seismic vulnerability analysis of shield tunnels considering cavitation
Rock and Soil Mechanics, 2021 The existence of cavities behind the segments is one of the common disease phenomena in shield tunnels. The cavities not only affect the static mechanics behavior of soil and segment, but also directly affect the dynamic response of the tunnel, which could aggravate the tunnel’s seismic damage.
