Hierarchical coding system of tunnel engineering for highway maintenance informatization

With the constant promotion of the “comprehensive and accurate” highway maintenance policy, the demand for application of tunnel maintenance informatization is expanding, and the standardization of hierarchical coding for the tunnel engineering is critically urgent. In this paper, the hierarchical informatization and coding system of related industries are analysed firstly, and then the hierarchical coding structure and classification code with high accuracy on the level of structural units and affiliated facilities are designed according to the combination of highway tunnel properties and maintenance characteristics. At last, the modular congruence algorithm is adopted for automatic verification, and a set of hierarchical coding system for highway maintenance information is preliminarily established. Furthermore, the research of the hierarchical coding system application has laid a solid foundation for the whole life cycle maintenance management of highway tunnel.
