Effect of soil conditioning on the permeability of coarse-grained soil in mechanized tunnelling

Heliyon, 2023
In coarse-grained soils, the reduction of soil permeability via conditioning can effectively prevent groundwater from entering the chamber, thus providing better tunnel face control and ultimately preventing excessive settlements of the surface.
