活动桥作为一种特殊的桥梁型式,越来越多地被用于流经城市的通航河流上以及水利工程中的通航建筑物上.活动桥的特点是桥体下方不需预留固定的通航净空,降低桥墩的高度,缩短两岸的引桥长度,简化桥梁的平面布置以节省占地空间.本文结合长江三峡水利枢纽升船机活动桥设计实例,介绍了水利工程中活动桥的设计思路.

The movable bridge, as a specific bridge type, is more and more widely used on navigable rivers in urban areas andnavigation structures of hydro-projects. The movable bridge has the featuresthat no navigation clearance is?required under the bridge body, lower the height of piers, shorten bridge approaches connecting both banks, and sim?plifythe plane layout of bridge and save land occupation. This paper, based on the practical application ofship lifting machine movable bridge designinthe Yangtze River Three Gorges Project, introducedthe design methodology of mov?able bridge for hydro-projects.
