摘　　要：采用了基于三维真实感图形学的OpenGL图形技术,建立了面向非线性有限元空间结构数值分析的接口,设计和实现了施工过程数值分析结果的三维可视化软件———大型钢结构施工全过程跟踪仿真软件.软件的仿真结果具有三维真实感,提供轴线模式、内力模式、截面模式、真三维模式等多种显示模式,以及起吊、悬臂拼装、滑移、张拉、整体卸载等多种施工模式的仿真.软件提供交互观察和查询功能,仿真结果的几何及力学指标均真实准确,效果直观.软件已成功地模拟了卢浦大桥和北京奥运主场馆工程的施工全过程.3D-visualization of numerical analysis of large-scale steel structures in construction is realized on the basis of OpenGL, which is a popular 3D-graphics API. And an access to the non-linear finite analysis of steel structures is built in the system. The simulation software covers the whole process of construction, providing multi-display modes such as axis-mode, internal-force-mode, section-mode and 3D-mode. It is also fit for multi-construction-technology, including lifting, slipping, unloading and straining; the software is interactive, and can accurately reflect geometrical and mechanical informa- tion of the steel structure. The software has succeeded in simulating the whole process of construction of Lupu Bridge and Peking Palaestra.
