Aiming at the problem of high quality and safety risk of corrugated plate reinforcementconstruction in complex environment, an efficient management method based on digital twin is proposed.Taking the reinforcement construction project of newly built Yuzhong Railway as an example, theconstruction difficulties caused by geological characteristics are analyzed. The application value of digitaltwin is summarized according to the construction difficulties and the technical concept of digital twin. Onthis basis, the construction management framework of corrugated plate reinforcement based on digital twinis systematically proposed. Based on the time line of the whole construction process, a digital twin five-dimensional model integrating pre-planning, real-time monitoring, simulation prediction, risk assessmentand post-optimization is established. Driven by this theoretical method, the optimization of constructionscheme and the control of quality and safety are realized. Aiming at the construction process, thetechnical analysis driven by the twin model is carried out for the two main construction processes ofcorrugated steel plate processing and installation. The practice shows that the proposed theoretical methodcan effectively improve the construction efficiency and quality, reduce the construction cost and ensurethe construction safety.
