基坑工程有限元数值分析结果的可视化表达

Visualization of finite element numerical analysis results in foundation pit engineering

针对基坑工程的施工力学特性,采用双扫描线提出有限元数值计算结果可视化后处理方法,在阐述了双扫描线方法的基本原理和实现方法的基础上,编制了可视化后处理类程序,并整合到所开发的基坑开挖有限元分析程序中。最后,对某一开挖基坑计算结果进行了处理,得到了满意的效果。

The procedure of visual post process based on double scanning beams method is proposed considering the characteristics of construction mechanics in deep foundation pit engineering. The principle and the implementation procedure of the double scanning beams method are presented. The programming for visual process class is made and the class is incorporated into the objective-oriented program for finite element analysis of deep foundation pit excavation and bracing. Through a numerical example of deep foundation pit, it is shown that the processing effect by the proposed method is perfect.
