基于Three.js的隧道参数化计算与可视化系统研究

Research on Three.js-Based Tunnel Parametric Calculation and Visualization System

随着BIM技术的兴起,参数化设计与可视化已成为盾构隧道新的发展方向。目前基于BIM技术建立的三维模型须通过C/S架构进行查看与交互,这种交互方式不具有“轻量化”、“大众化”、“简单化”的特点。本文将BIM技术与Three.js技术应用于盾构隧道,基于B/S架构建立了盾构隧道参数化计算与可视化系统。该系统集基本模型展示与交互、荷载计算、配筋计算、盾构施工过程模拟于一体,实现了盾构隧道的参数化计算与BIM模型的轻量化跨平台展示,增强了盾构隧道的可视化与交互性。

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.
