摘　　要：上海2010年世博会的世博轴项目是首次将阳光谷、索膜屋面结构及地下暗渠等设计元素大规模应用于建筑单体。它独特的建筑造型决定了雨水排水系统的特殊性,其中膜屋面排水和地下雨水调蓄系统是主要设计难点。在分析和解决过程中,将安全性作为首要原则考虑,同时兼顾美观、经济和生态环保等相关因素,最终形成了各方都能够接受的系统解决方案,包括安全美观的膜屋面节点构造形式、合理的蓄水容积、适当的排水能力、可靠的应急措施,以及简单、易于操作的管理策略。In the Expo Axis project of World Expo 2010 Shanghai, it is the first time that elements such as sunny valley, membrane roof structure and underground reservoir are applied to a single building on a large-scale. Its unique architectural style determines the particularity of rainwater drainage system. Membrane roof drainage and underground rainwater storage system are the main design difficulties. In the analysis and solution process, the security of the building is considered as the first principle, while taking into account the aesthetic, ecological and economic factors as well. Finally, fully acceptable and system- atic solutions are reached, including safe and aesthetic membrane roof drainage point structure, reasona- ble storage volume, proper drainage capacity, reliable emergency measures, and a simple workable management strategy.
