基于物元模型的地铁BIM设计风险评价

BIM Risk Assessment of Subway Design Based on Matter Element Model

BIM技术在轨道交通行业的探索与应用是亟待解决的新问题。基于可拓学的物元模型,着重选取地铁设计阶段为研究对象,通过流程图法从技术、人力资源、资金、行业标准与管理5个方面识别出阻碍地铁设计应用BIM技术的主要风险因素,在此基础上构建二级评价指标体系。以兰州地铁1号线为案例背景,利用物元模型对已构建的指标体系进行评价分析,找出阻碍BIM在轨道交通业发展的根源因素,并提出相应的改进措施,从而促进新技术在轨道交通行业的应用与发展。

The exploration and application of BIM technology in railway transportation industry is a new problem. Based on the matter-element model of extenics, focusing on design stage of selected metro project, main risk factors from five aspects, human resources, capital, industry standards and management, are identified using method of flow chart. Taking Metro Line I of Lanzhou as the case, the constructed index system is analyzed using matter-element model. Factors that impede the development of BIM in the rail transportation industry are identified. Finally, corresponding improvement measures are presented to promote the new technology in the field of rail transportation.
