With the rise of BIM technology,parametric design and visualization have become a new development direction for shield tunnels.At present,the three-dimensional model established based on BIM technology must be viewed and interacted through the C/S architecture,this interaction mode does not have the characteristics of"lightweight","popular"and"simplified".In this paper,BIM technology and Three.js technology are applied to the shield tunnel,and a parametric calculation and visualization system for the shield tunnel is established based on the B/S architecture.The system integrates the basic model display and interaction,load calculation,reinforcement calculation,and shield construction process simulation,realizes the parametric calculation of the shield tunnel and the lightweight cross-platform display of the BIM model,and enhances the visualization and interaction of the shield tunnel.
