摘　　要：本文介绍大口径预应力钢筒混凝土管(PCCP)在长距离输水管线中的应用,以及工程设计时,对管材的选择、管材结构设计标准的选择、配件设计、管道软土地基的沉降分析及处理、止推设计及沟槽支护的做法等的研究和讨论,供类似工程参考。The application of large diameter PCCP in the long distance transmission pipeline was introduced. At the meantime, the key design parameters such as the selection of pipe materials, the selection of pipe structure design standard, the design of fittings, analysis and processing of soft soil foundation settlement, thrust design and groove supporting practice, etc. were also researched and discussed. It could be referenced by the similar project.
