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.

Real‐time multiscale characterization of water migration in deep coal under stepwise pressure‐increasing injection: Combined low‐field nuclear magnetic resonance and multifractal approach

Deep Underground Science and Engineering, EarlyView.
The graphical abstract illustrates the real‐time multiscale characterization of water migration in deep coal under stepwise pressure‐increasing injection. Under in‐situ hydrostatic pressure, the water invasion front advances progressively along the axial direction as the injection pressure increases stepwise, tracked in real time by nuclear magnetic ...

A Perspective on Five‐Generation High‐Energy‐Density LiFePO4 Cathodes and Beyond: From Materials to Manufacturing

EcoEnergy, EarlyView.
This perspective examines the evolution toward fifth‐generation LiFePO4. Practical volumetric energy density depends on preserving ionic transport, electronic connectivity, mechanical integrity, and active‐material utilization across powder design and manufacturing.
