摘要

皮河高架桥是长江引水工程的一个里程碑。从结构上看，它是一个跨度为(68+110+68)m的梁拱组合体系。这是中国第一座钢结构渡槽。其通航渡槽跨度居世界首位。本文首先从施工条件出发，对其选址、荷载特征、结构类型、耐久性进行了探讨，并给出了相应的概念设计。通过大量的科学研究和试验，验证了设计方案的可靠性，并从研究和试验中总结出详细结构设计的指导思想。

Design of the Main Structure of The Pi River Water Viaduct

The Pi River Water Viaduct is a milestone in the Yangtze-to-Huai Water Diversion Project. From the structure point of view, it is a girder-arch composite system with a span configuration (68+110+68)m. It is the first aqueduct made of steel structures in China. And its span ranks the 1st in the world in terms of navigable aqueducts. Site selection, load features, structure type, durability are firstly discussed in the paper on the basis of construction conditions, and then a corresponding conceptual design is given. The reliability of the design solution is validated by a large number of scientific studies and tests, and guidance for detailed structural design is also summarized from the studies and tests.
