基于BIM的地铁车站算量系统研究

Research on the Quantity Calculation System of Subway Station Based on BIM

依托Revit平台,利用AutoCAD的.net API从地质柱状图CAD文件中提取地层信息,并自动识别地铁车站BIM模型中的基坑围护结构边界,得到各层开挖体量,从而生成土建工程的土石方工程数量表。利用RevitAPI和RevitAPIUI接口,提取BIM模型中机电系统设备与主材参数得到工程数量表,并按照国家工程量清单计算规则进行自动计价,从而生成标准格式的设备与主材工程量清单。实践证明,基于BIM的地铁车站算量系统可提高设计效率和文件质量,可以应用于地铁车站工程量计算。

Relying on the Revit software,this paper collects the strata information from the boring log CAD file with.net API of AutoCAD.Then,identifies automatically the boundaries of the foundation pit retaining structures in BIM model,and obtains the excavation volume of each stratum and the engineering quantities of earthworks.By using Revit API and Revit APIUI,collects the parameters of the mechatronicdevices and materials in Revit BIM model,and generates the standard bills of engineering quantities according to the national standard.Practice has proved that the quantity calculation system can promote the design efficiency and the report quality,and can be popularized in the quantity calculation of the subway station.
