管道运输方式在疏浚工程中使用比较普遍。在急流区域疏浚时,减少水流对管线的作用力成为保证整个管线运输系统安全运行的关键问题。文章运用理论分析的方法,对水中浮管与浮舟托管两种型式的管线受力进行了计算、比较,并对浮舟托管管线的构成提出了建议。

Pipelines are widely used in transportation of dredge spoil.When dredging in the quich current areas,reducing the external force on the pipeline is the key to maintain the normal and safe operation of the pipeline transportation system.The external forces on the two types of pipelines,namely floating pipeline and pipeline supported on pontoons,are analyzed and compared with the theoretical analysis method.Suggestions on the composition of the pipeline supported on pontoons are made.
