摘要
传统的公路施工场地临时设施的布置方案主要是依靠专家经验来完成,但在布置方案的设计过程中由于施工现场的地形地势条件复杂,有关专家对现场的地理特征缺乏全面的了解,容易造成场地布置方案不适合实际的施工过程,带来工期和成本的损失。为了使专家的施工经验可以更直观地展现在场地布置设计方案中,本文融合建筑信息模型(BIM)技术和虚拟现实(VR)技术,构建了交互式、可视化的施工场地临时设施布置决策辅助系统,描述了系统的架构和模块,以及应用流程及功能。该系统借助虚拟现实技术构建临时设施布置情境,使施工现场布置方案决策人员能够从总体到局部对整个工程的施工情况进行精确把控,避免决策失误,以达到科学合理地布置施工临时设施。
The layout plan of temporary facilities for traditional road construction sites is mainly based on expert experience.However,due to the complicated terrain conditions of the construction site during the design of layout plans,it would be difficult for experts to attain a comprehensive understanding of the geographical features of the site,which could lead to poor onsite plans not applicable to the actual construction process with higher cost and longer schedule.In order to integrate the experts'experience in layout planning in a more visulised way,this research integrates Building Information Modelling(BIM)and Virtual Reality(VR)to construct an interactive and visualized site layout decision supporting system for highway construction.In this paper the framework and modules of the proposed decision supporting system as well as the application process and its functions are described.The virtual reality technology is used to construct the temporary facility layout in the real scene models,so that the decision makers could accurately control the construction of the entire project from the whole to details,avoiding mistakes in decision-making,and achieving scientific and rational layout of temporary facilities.
