Design and implementation of Aqueduct Bridge with Combined Type of Arched Girder

拱梁组合式渡槽是90年代发展起来的一种新型渡槽结构型式，它具有构件轻巧、受力状态良好、外型美观、便于施工、安全可靠、经济适用等特点，是一种较好的渡槽结构型式。目前已在国内一些地区开始推广使用。本文介绍了拱梁组合式渡槽的特点、适用围及若干设计与施工的要点。

As one of modern aqueduct bridge structures developed in the 1990s and with the eharateristics of light in weight,fair performance under extra forces, good outhne, safe and convenient for implementation,economic for application, and so on, aqueduct bridge with combined tpe of arched girder is presenily extensively applied in the domestic and abroad regions .The features, application range, and key points for design and implementation of aqueduct bridge with combined type of arched girder are introduced in the paper.
