📄 Abstract(原文)
Energy underground structure technology holds significant importance for energy conservation and emission reduction in the building sector. Utilizing heat exchange pipes and underground structures as venues for geothermal energy exchange is expected to establish a sustainable energy system serving resilient cities. However, the impact of long-term intermittent operation of energy tunnels on the temperature recovery capacity of surrounding soil has not been adequately studied. This study takes...
