Stability Analysis of the Surrounding Rock of Deep Underground Engineering Under the Action of Thermal-Solid Coupling

Buildings
When developing deep subsurface infrastructure in areas with intense geothermal activity, the significant temperature gradient inevitably leads to low-temperature contraction and high-temperature expansion of the rock body, resulting in changes in the rock’s mechanical properties.

Study on Heat and Moisture Transfer Characteristics During Fresh Air Introduction in Deep Underground Engineering

To clarify the heat and moisture regulation mechanism of deep-buried underground air tunnels and address the research gaps in the heat and moisture coupling between airflow and surrounding rock. This paper established a 560 m-deep ventilation shaft with a diameter of 5 m focused on the heat and moisture transfer of "surrounding rock - air ...
