Hydro-mechanical analysis of tunneling in saturated ground using a novel and efficient sequential coupling technique
In 1941, Belgian-born physicist Maurice Anthony Biot (1905-1985) developed the first equations that govern the coupled interactions between fluid flow and deformation in elastic porous media. This hydro-mechanical (H-M) interaction has started to receive wide attention in the field of tunnel engineering. In urban areas, the induced H-M interaction due to surface loading over an existing shallow tunnel can have a severe impact on short- and long-term tunnel stabilities, the degree of which remains unclear. Likewise, advancing tunnel in deep saturated ground causes time-dependent consolidation ...
