摘　　要：管道分段设计是长输管道工程制图的起点,传统的分段设计方法,主要采用手工的布置方式,虽能充分发挥设计人员的主动性,但由于线路一般长达上百公里,致使设计速度慢,效率不高,影响了后期的制图工作进度。本文针对管道分段的问题,借鉴线简化的思路和方法,在分析管道线路分段设计需要和特点的基础上,提出一套管道线路自动分段设计的方案,辅助分段设计工作,并利用ArcEngine实现了一个实例,与传统的分段方法进行比较,证明方案的可行性和有效性。In the area of long distance pipeline,pipeline section design is the first step to design engineering sheet and map.Since pipelines are always hundreds of kilometers,traditional design method,which can take advantage of designers＇ subjectivity,causes low work efficiency and has an impact on post-mapping process.According to the way of line simplification and the characters of pipeline section design,this paper proposed a method to realize pipeline cutting up,which can aid pipeline section design work in a more effective way.Finally,this paper used ArcEngine to implement the program,and compared its result with that of traditional method to prove its feasibility and effectiveness.
