Resumen
Information management is an important development direction in the field of tunnel engineering, and BIM technology provides an important approach for the realization of it. However, standardization is the first step of the implementation of BIM technology. Only through a set of unified BIM standards for tunnel engineering can the late platform development with information sharing and exchange be carried out normally and orderly. In view of the current lack of unified BIM technology standards and related theoretical research in the field of tunnel engineering, this paper proposes a theoretical framework for the study of a BIM technology standard in the field of tunnel engineering on the basis of the existing standardization research work and establishes a new maturity model in the field of tunnel engineering for the first time. On this basis, this paper classifies and codes the information in the field of tunnel engineering and carries out a series of preliminary studies and discussions on the standardization of BIM technology in the field of tunnel engineering, initially establishing a relatively complete system of BIM technology standards. With the Daliangshan Tunnel under construction in Sichuan Province of China as a pilot application case, the feasibility of the proposed standards is preliminarily verified. In addition, this paper puts forward the new concept of ?standard degree? for the first time and tentatively discusses the relationship between the standard degree and four influencing factors, the standard unity degree, the recognition degree of project participants, the applicable degree of software and the perfection degree of platform construction, which provides a reference for subsequent related research and promotes the development of BIM technology standardization and the management process of information in the field of tunnel engineering.
