Probabilistic characterization of seepage‐induced tunnel face failure via a two‐phase double‐point material point method

Deep Underground Science and Engineering, EarlyView.
To address seepage‐induced tunnel face collapse, this study develops a two‐phase double‐point MPM framework to capture large‐deformation hydro‐mechanical interactions. Incorporating a cementation‐based constitutive model with dynamic permeability updates, the model is successfully validated against saturated granular‐column collapse experiments ...

Numerical investigation of natural fracture activation and leakage risk during CO2 sequestration in depleted sandstone reservoirs

Deep Underground Science and Engineering, EarlyView.
This study investigates the hydro‐mechanical response and fracture evolution in depleted sandstone reservoirs during CO2 injection, considering both direct wellbore injection and hydraulic‐fracture‐assisted injection. The graphical abstract illustrates how CO2 injection induces dynamic stress redistribution, leading to natural fracture activation ...

Investigation on the mechanical behavior of the multiple‐layered lining structure of a water conveyance tunnel with high internal water pressure

Deep Underground Science and Engineering, EarlyView.
This study presents large‐scale similarity model testing (geometric ratio 3.6) of an innovative multiple‐layered lining system—comprising exterior precast segments, middle self‐compacting concrete, and an interior steel pipe—for high‐pressure (0.75 MPa) water conveyance tunnels.

Energy evolution‐based damage quantification and failure prediction of fault zone tunnel lining concrete: A novel acoustic emission–strain energy coupling approach

Deep Underground Science and Engineering, EarlyView.
This study investigates the damage evolution and failure mechanisms of tunnel lining concrete in active fault zones through uniaxial compression tests integrated with acoustic emission (AE) monitoring. A strong linear correlation is identified between the AE cumulative absolute energy and the total strain energy, providing a reliable energy‐based ...
