Study on the composite fracture characteristics of filling and reinforcing cracked rock mass after high temperature damage

open access: yesDeep Underground Science and Engineering, EarlyView.
Cement infill shares compressive and shear stresses during loading, while interfacial friction hinders crack propagation and reduces stress concentration, improving the rock's load‐bearing capacity. Failure modes vary with crack inclination. Unfilled specimens show four modes.

Numerical simulation study on the evolution of the temperature field and frozen wall in fractured rock mass

open access: yesDeep Underground Science and Engineering, EarlyView.
The evolution of the temperature field and frozen wall under different fracture conditions was examined by an artificial ground freezing‐based thermal‐hydraulic coupled model. It was observed that fracture inclination affects the interaction extent of freezing pipes and fracture, while phase transition extent is the dominant factor for heat transfer in

Analytical stress solution framework for lined compressed air energy storage chambers and its application to safe burial depth determination and supporting effectiveness evaluation

open access: yesDeep Underground Science and Engineering, EarlyView.
An analytical framework delivers a closed‐form stress solution for lined compressed air energy storage chambers, enabling the determination of the minimum safe burial depth. The solution quantitatively evaluates lining support effectiveness, offering a reliable tool for chamber design and optimization.

Unravelling the Policy‐to‐Implementation Gap: Climate Adaptation Governance Arrangements in Medium‐Sized Cities

open access: yesEnvironmental Policy and Governance, EarlyView.
ABSTRACT Urban areas are increasingly facing climate‐related risks that outpace the implementation of adaptation measures, often attributed to a persistent policy‐to‐implementation gap. Bridging this gap requires a deeper understanding of the underlying governance dynamics.
