基于6D BIM技术的双壁钢围堰碳足迹计算模型及应用研究

Research on Carbon Footprint Calculation Model and Application of Double-walled Steel Cofferdam Based on 6D BIM Technology

在我国的“双碳”政策背景下,6D BIM(Building Information Modeling,建筑信息模型)作为近年来的热门技术正处于飞速发展阶段。以某工程采用的双壁钢围堰为例,阐述了6D BIM技术在工程实际中的应用。通过Revit软件建立3D模型,进行碰撞分析,并利用C#语言实现了Revit模型向Midas Civil模型的转换。依托Fuzor软件和Navisworks软件,完成了4D BIM和5D BIM的建立,对各阶段资源消耗进行统计,使钢围堰施工进度与资源消耗智能化、可视化。采用全生命周期评价(life cycle assessment,LCA)对碳排放进行测算,建立碳足迹计算模型,并对QT Creator集成开发平台进行二次开发,开发碳足迹计算系统、建立碳足迹因子库,实现6D BIM技术,为绿色建筑、低碳建筑的探索和实现提供参考。

Under the background of dual carbon in China,6D BIM as a hot technology in recent years,is in a stage of rapid development.Take a double-walled steel cofferdam used in a certain project as an example to explain the application of 6D BIM technology in engineering practice.The 3D model was established through Revit,the collision analysis was performed,and the Revit model was converted to the Midas Civil model using the C#language.Relying on Fuzor and Navisworks software,the establishment of BIM 4D and 5D models was completed,and the resource consumption at each stage was statistically counted,so that the construction progress and resource consumption of the steel cofferdam were intelligent and visualized.The life cycle assessment(LCA)is used to measure carbon emissions,establish a carbon footprint calculation model,and carry out secondary development of QT Creator integrated development platform,develop a carbon footprint calculation system,and establish a carbon footprint factor library.Realize 6D BIM technology to provide reference for the exploration and implementation of green buildings and low-carbon buildings.
