Leakage risk assessment system for salt cavern hydrogen storage

Deep Underground Science and Engineering, EarlyView.
Establishment of a leakage risk evaluation system for salt cavern hydrogen storage reservoirs using the entropy weight method plus two‐dimensional cloud modeling approach. Abstract Salt cavern hydrogen storage (SCHS) is an important component of large‐scale underground hydrogen storage, with advantages such as large hydrogen storage capacity and ...

Data‐driven analysis of the spatial dependence of grouting efficiency during tunnel excavation

Deep Underground Science and Engineering, EarlyView.
Prediction of grouting efficiency using machine learning is enhanced by adopting a training strategy that accounts for the grouting process across multiple rounds. Abstract Grouting with water–cement mixtures is the most widely used and cost‐effective method for managing excess water inflow during tunnel construction.

Random finite element analysis on ground subsidence caused by tunnel excavation in karst regions with spatial variable soil

Deep Underground Science and Engineering, EarlyView.
This study investigates ground subsidence during tunnel excavation in karst areas, highlighting the combined effects of karst cave proximity, cave size, and soil spatial variability. Findings suggest that shorter cave distances and larger cave sizes increase subsidence variability, and a modified Peck formula is proposed for more accurate subsidence ...

Stability analysis of a compressed air energy storage cavern transformed from a horseshoe‐shaped roadway in an abandoned coal mine

Deep Underground Science and Engineering, EarlyView.
Stability analysis of compressed air energy storage caverns transformed from horseshoe‐shapes roadways in an abandoned coal mine is carried out. Both initial damage areas and two cavern shapes are numerically simulated using a one‐way coupling iteration algorithm of an improved generalization α method.
