地下管线竣工测量中交叉问题的探讨

Discussing on the Problems of Crossing in Finish Underground Pipelines Survey

地下管线竣工测量是城市规划、建设和管理的基础资料,是地下管线安全运行的保证。利用CAD的二次开发工具lisp语言,在CAD平台上开发了一套管线检查程序,实现地下管线竣工测量数据的快速检查,及时地发现问题,解决问题,确保地下管线竣工测量成果的逻辑关系合理,为数据顺利入库提供保障。本文着重介绍管线数据在CAD上的表现形式、管线交叉程序的设计过程和源代码、程序加载方式及结果显示。

Acceptance survey of underground pipeline can not only provide basic data of urban planning, urban con- struction and administration, but also guaranty the safe run of underground pipeline. Using lisp language of CAD, a set of program of pipeline survey was developed and it can fast check the acceptance survey data of underground pipeline. It could find and solve problem in time, guaranty the reliability of the acceptance survey result of underground pipeline and finally provide the input of data. This paper mainly introduced the performance form of pipeline data on CAD software, the design process of pipeline cross program, and source code, program loader and result illustration.
