摘　　要：为促进城市地下管线规范化、科学化管理,配合城市地下管线探测和地下管线信息管理系统的建设,实现数据共享,需要建立统一的数据编码规则。本文从目前广泛应用的几种编码方法出发,提出了一种便于数据管理、查询、网络分析及满足系统实际需求的编码方法,为管网系统的规范化建立提供参考依据。An untorm data coding regulation should be constructed to meet the need of scientific and standardized management of underground pipeline, as well as data sharing and construction of underground pipeline systems. By analyzing of widely used coding methods, a new method is proposed in this paper, which can perform many functions easily, such as data nlanagement, searching, and analysis. It provides a reference for standardized construction of underground pipeline.
