Intelligent inversion analysis of dilatancy angle of surrounding rock based on the force of negative Poisson's ratio anchor cable

Deep Underground Science and Engineering, EarlyView.
An intelligent inversion framework estimates the dilatancy angle of the surrounding rock from negative Poisson's ratio (NPR) anchor cable force histories. Numerical tunnel‐excavation simulations generate force data across a controlled dilatancy‐angle range, which are mapped to the target parameter using a sequential convolutional neural network (CNN ...

A hierarchical adaptive strategy for selecting rheological models in intelligent backfill mining pipeline transportation systems

Deep Underground Science and Engineering, EarlyView.
This graphical abstract presents a hierarchical adaptive strategy for selecting rheological models in intelligent backfill pipeline transportation. Temperature, fly ash content, and water‐cement ratio jointly influence slurry rheological nonlinearity, which is quantified using the Model Fidelity Gain (ΔR2).

Transcriptome and proteome analyses reveal divergent adaptive strategies in nasopharyngeal epithelial cells and nasopharyngeal carcinoma cells under ultra‐low background radiation

Deep Underground Science and Engineering, EarlyView.
This study demonstrates that the ultra‐low background radiation environment in deep underground laboratories significantly inhibits the proliferation of both normal nasopharyngeal epithelial cells (HNEPC) and nasopharyngeal carcinoma cells (HNE‐1) cells, with malignant cells exhibiting higher sensitivity.

Three‐dimensional hardening‐softening elastoplastic modeling of nondilatant rock‐like materials with nonorthogonal flow rule

Deep Underground Science and Engineering, EarlyView.
A novel three‐dimensional elastoplastic constitutive model is developed for nondilatant rock‐like materials under true‐triaxial stress conditions. A piecewise yield function captures the evolution of 3D yield surfaces during hardening‐softening processes, while a fractional‐order‐controlled nonorthogonal flow rule enables flexible regulation of ...

Steel segment–anchor bolt (cable) structure for TBM tunnels under extremely intense rockburst conditions: Design method and field application

Deep Underground Science and Engineering, EarlyView.
The graphical abstract presents a steel segment–anchorage support system for open TBM tunnels under extremely intense rockburst conditions. The steel segment resists dynamic impact, while the anchorage structure restrains segment deformation and transfers loads into the rock.
