Abstract: The pipeline aerial crossing in Bapanxia of Yellow River for Sebei-Xi'ning-Lanzhou Gas Transmission Pipeline is a large-scale crossing, its span is the largest one in the same type of crossing of the pipeline bridge. The engineering design and the aerial crossing are very difficult due to the deep water with turbulent wave. The feasibility study on the design is carried out in the light of the determination of design scenario, structural calculation, selection of steel members and implementation of construction procedure. The comparison between several aerial crossing scenarios is conducted. The last candidate is the suspension pipeline bridge. In this article, the design process of the pipeline aerial crossing in Bapanxia of Yellow River is introduced. The author considers that the design experience can be used in the design of the same type aerial crossing of pipelines.
