摘要:白沙长江大桥为采用跨径布置为590m+180m的两跨半漂浮地锚式悬索桥。该项目具有涉及专业广、结构构造复杂、施工工序繁多等特点,需借助BIM正向协同设计手段以确保设计产品质量。为避免BIM模型在不同软件传递过程中的信息丢失,首次提出“R+GH+ARQ”——基于同一软件平台下开展协同正向设计。本文阐述了设计阶段全过程BIM设计分析与应用,以及通过定制化二次开发实现地质快速剖切成图及计算模型交互、云计算引入、施工仿真、移动端应用等技术,以提升BIM模型的附加值,拓展BIM技术的产品服务链,为BIM技术在同类型桥梁正向设计的应用提供参考。
Abstract: The Baisha Yangtze River Bridge adopts two-span semi-floating ground anchor suspension bridge with span of 590m+180m.This project possesses characteristics of a wide range of disciplines, complex structure and various construction processes, and it is necessary to make use of the forward cooperative design means of BIM model so as to ensure the quality of design products.In order to avoid the loss of information in the BIM model in the process of different software transmission, "R+GH+ARQ" is first proposed, which is a method based on the same software platform to carry out collaborative forward design.This paper describes the design analysis and application of BIM technology in the whole design process, which realizes the geological rapid cutting mapping and computational model interaction, introduction of cloud computing, construction simulation, mobile application and so on through customized secondary development, so as to enhance the added value of BIM model, expand the product service chain of BIM technology, and provide reference for the application of BIM technology in the forward design of the same type of bridge.
