长庆油田陕北区块地处黄土高原,油区内沟壑纵横,地形极其复杂,在油田产能建设地面工程中,管网铺设路线上常有山谷、河流等障碍物,这种环境为管道铺设带来了很大的问题。由于地形限制、穿越长度过大而无法进行正常施工,就需要以跨越的方式完成管道施工。大跨度跨越工程多数采用悬索结构形式,这种结构形式较复杂,施工难度大,本文就大跨度悬索管道的跨越施工进行了深入分析。 Changqing Oilfield in northern Shaanxi block is located in the Loess Plateau, ravines vertical and horizontal oil region, the terrain is extremely complex, in the oil field construction capacity of the ground works, pipelines often laying valleys, rivers and other obstacles, this environment for the pipe laying Brought a big problem. Due to the limitation of the terrain, the crossing length is too large to carry out the normal construction, and the pipeline construction needs to be completed by leaps and bounds. Large-span spanning projects mostly adopt the form of suspension cables. This kind of structure is more complex and difficult to construct. This paper analyzes the span construction of long-span suspension cables in depth.
