Abstract:

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.

Key words: civil work structure of tunnel, operation management system of tunnel (tunnel groups), data classification, coding
