Abstract: Two new types of super-span pipe bridges are discussed in this paper. One is a suspension pipe bridge of catenary curve type and the other is a cable stayed pipe bridge. Compared with the conventional suspension pipe bridges, they have the following advantages: (1) providing the longest span; (2) no necessity of winding wire systems; (3) costs lower than other suspension pipe bridges; (4) good winding resistance stability and resisting vibrations easily with only a few simple wires; (5) convenient for erection and assembly, not obstructing the normal inland navigation under it. This paper briefly describes the component configurations, model tests, design considerations and analyses, as well as erection methods etc. of these two tvpes of bridges.

摘要： 随着我国油、气管道建设的发展,在管道建设中常常遇到河流、沼泽、湖泊、山谷等自然障碍物或人工构筑物,不得不采用穿越或跨越形式敷设。但常常由于河床不稳定,河床或边坡冲刷严重,开挖管沟十分困难或不经济等原因,而采用空中跨越要比水下穿越更为合理。管道跨越大江大河,施工复杂,技术难度大,国外大跨度管桥大都采用悬索管桥
