中文摘要：

为了满足沪蓉西高速公路隧道（群）运营管理系统中数据库的建设需求,对隧道土建结构数据进行分类和编码研究。根据隧道建设的全生命周期,将数据按勘查阶段、设计阶段、施工阶段和运营阶段进行分类,并采用层次代码结构进行编码。实践表明：该数据分类与编码体系基本可以涵盖隧道全生命周期中所有的土建结构元素数据;可以满足隧道（群）运营管理系统中数据库建设的需要;可以为其他系统数据的分类与编码提供有益参考。

英文摘要：

Analysis is made on the classification and coding of the data of the civil work structures of tunnels in order to meet the requirements to establish the database for the operation management system of tunnels（tunnel groups） on Shanghai-Chengdu highway.The data are divided into 4 stages,i.e.,survey stage,design stage,construction stage and operation stage,on basis of the complete life of the tunnels,and are coded by means of hierarchical structure.Long-term practice shows that the system of classification and coding could almost cover all the data of the civil works in the complete life of tunnels,could meet the requirements of the operation management system of the tunnels（tunnel groups） and could provide reference for the classification and coding of the data of other systems of tunnels.
