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

Deep 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.

A New Classification Method of Surrounding Rock Quality for Phyllite Tunnels Under the Condition of Layer Orientation Parallel to the Orientation of Tunnel Axis

Energy Science &Engineering, EarlyView.
Modified Mass Classification of Layered Rock Masses Based on the HC Method. ABSTRACT The HC method for hydropower is a commonly used rock mass quality classification technique in China's hydropower industry. Due to the anisotropic nature of the layered schist in the study area, and the varying angles between different tunnel layers and the tunnel axis,

Design and Optimization of Cleanroom Systems From an Energy Perspective

Energy Science &Engineering, EarlyView.
Using MATLAB‐based modeling, this study optimizes HVAC energy use in pharmaceutical cleanrooms with plastic injection machines. Results show optimal fresh air and ACH settings for winter (50%, 50) and summer (90%, 40/25 for class C/D). Adaptive control of ventilation further enhances efficiency.
