摘要
针对钢管混凝土拱桥拱肋吊装施工特点和控制要求,提出了按照迭代前进算法对拱肋拼装过程进行仿真计算的可视化实现模式。并且介绍了利用可视化技术进行仿真计算能够形象地再现现场,快捷地实现对拱肋吊装施工进行吊装预测、现场实时监控,为施工控制提供了有效的手段。
With reference to the characteristics and control requirements for erection of arch ribs of the concretefilled steel tubular arch bridges, this paper presents a visual implement mode of simulation computation of arch rib assembling process according to iterative goahead method, and illustrates that the simulation computation using the visual implement techniques can vividly reproduce the situations at construction site, rapidly realize predicting of arch rib erection and realtime monitoring, and thus provides construction control with effective means.
