基于BIM的地铁车站实时施工模拟与应用研究

Real-time construction simulation and application research of subway station based on BIM

针对地铁车站施工过程中多方协调难度大、施工进度和成本控制要求高以及施工安全风险实时响应不及时等问题,以BIM三维建模技术为基础,探索BIM与信息技术和计算机图像技术的结合点,重点研究BIM的自动更新技术,提出基于BIM的实时施工模型以及基于模型的地铁车站实时施工模拟流程。实时施工模型的自动创建可以将现场采集的数据自动识别到计算机系统中,通过特征提取、分类匹配形成参数化构件,并实施更新到BIM模型当中,从而进行实时的施工模拟。结合长沙地铁实际工程,将实时施工模型应用到实际工程施工阶段当中。

Difficult for metro station construction in the process of multilateral coordination,construction schedule and cost control requirements and construction safety risk problem such as real-time response is not timely,the paper is based on BIM 3D modeling technology,and explore the BIM and information technology of computer image technology combining site.The paper focus on BIM model automatically update technology,real-time construction based on BIM model and the construction process based on the model of subway station real-time simulation was put forward.Real-time construction model can be automatically created to automatically identify the data collected in the field to the computer system,through feature extraction,classification,matching,to form parametric components,and implement updates to the BIM model for real-time construction simulation.At the same time,the application of real-time construction simulation based on BIM in Changsha metro project were studied.
