As property development above vehicle depots becomes increasingly common, it's crucial to address the construction and operational challenges this poses to the underlying facilities. This necessitates adaptive adjustments and optimizations in various aspects of depot design, including overall layout, fire safety, traffic management, utility systems, and vibration and noise mitigation. By comparing developed and undeveloped vehicle depots, this study proposes an optimization strategy centered on "one core concept and two principles." This approach aims to create favorable conditions for aboveground development while safeguarding the underground facilities' safety and environment, without compromising the depot's scale and functionality. The study outlines optimization strategies across multiple areas, including site selection, layout planning, maintenance procedures, emergency evacuation, ventilation and smoke control, and traffic flow. Specific recommendations include improving stationsection relationships, maximizing land use efficiency, implementing advanced maintenance equipment, and enhancing evacuation and smoke management systems. The ultimate goal is to minimize the negative impacts of aboveground development, fostering a harmonious relationship between the aboveground and underground facilities for mutual benefit.
