为了解决车辆基地上盖开发对盖下引起的建设和运维问题，需对其总平面布置、消防、交通、管线、减 振降噪等各方面进行适应性调整和优化。通过分析车辆基地开发与不开发的差异性，以问题为导向，提出“一个 中心、两个原则”的优化策略，即在保证盖下规模和功能的前提下，既为上盖开发创造良好条件，又确保盖下安 全与环境，从选址、总平面布置、检修工艺、消防疏散、通风排烟、交通组织等各方面阐述优化设计思路，包括 良好的站段关系、整合集约用地、采用新型检修设备、加强疏散和防排烟等，尽可能消解上盖开发带来的不利 影响，从而实现盖上盖下相互协调、互利共赢。

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 above-ground 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 station- section 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 above-ground development, fostering a harmonious relationship between the above-ground and underground facilities for mutual benefit.
