［摘要］结合工程实例对车辆段盖上物业开发落地式、局部转换式和全部转换式三种结构转换方案进行了探讨，认为车辆段结构方案需统筹考虑盖下工艺条件和盖上开发建筑的规模，结合结构体系的高度和实用性、经济性，并与工程筹备条件相协调。提出如下建议：1）低烈度区尽量采用直接落地式，盖上的结构方案以混凝土框架最为理想；2）高烈度区在盖上开发体量较大，盖上结构层数较多时尽量采用局部转换式，以增加开发体量，取得最好的经济效果；3）高烈度区在盖上开发规模中等时，尽量采用隔震体系的全部转换式，使盖上的结构在二次开发时有一定的建筑方案调整余地。所涉及的隔震转换以及车辆段等的设计选型原则均是针对具体工程特点提出的，可供相似工程借鉴和对比。

Abstract:Combining with engineering examples, three kinds of structural transformation schemes of property development above metro depot, i.e. landing type, partial transformation type and total transformation type, were discussed. It was considered that the structural scheme of property development above metro depot should take into account the technological conditions of the lower part and the scale of the property development above metro depot as a whole, and combine the height, practicability and economy of the structural system with engineering preparation. The following suggestions were put forward: 1) the direct landing type can be adopted in the low seismic fortification intensity area, and the concrete frame is the most ideal structural scheme for the buildings above metro depot; 2) the partial transformation type can be adopted in the high seismic fortification intensity area when there are large development volumes and many stories of the structures above metro depot, so as to increase the volume of the development and achieve the best economic results; 3) the seismic isolation transformation can be adopted as far as possible when the development scale of the buildings above metro depot is medium, so that there are some room for adjustment of the building plan in the secondary development of the structures above metro depot. The principles of seismic isolation transformation and metro depot design and selection were put forward according to the specific engineering characteristics, which could be used for reference and comparison of similar projects.

Keywords:property development above metro depot; structural system selection; structural transformation; seismic isolation
