摘　　要：随着地下管线信息应用水平的提高,管线数据分别归属不同管理部门的状况,越来越难以确保综合管线数据的完整性、准确性和现势性.从城市地下管线信息系统的建设实践出发,结合分布式数据库的特点,提出一种综合地下管线分布式数据库的设计构想.探讨分布式数据库的架构设计、地下管线数据结构设计和元数据设计等技术难点,有效解决了管线数据分散存储与访问难题,并进行具体实现.结果表明,该方案应用效果良好,为城市综合地下管线的分布式管理与深入应用提供一种新思路.Advancements in the application of underground pipeline information led to the increased complexity in the design and implementation of the information management system. With the underground pipelines data being managed by many different government agencies,it becomes more difficult to ensure their integrity, accuracy and timeliness. In this paper, based on the practice on building urban underground pipelines information systems,a distributed database design scheme was proposed. In particular,the core design issues such as infrastructure design of distributed database, structure design of underground pipelines and metadata design were discussed systematically. The efficient solutions to the key implementation problems such as decentralized storage and access of pipelines data were provided. The proposed design scheme in a practical underground pipelines information system application was implemented. The real world application shows the effectiveness of our proposal and provides new insights for the further application of distributed management of integrated underground pipelines.
