摘要
利用BIM技术建立参数化、可视化和标准化的三维信息模型以便更加有效地利用地下空间已成为建筑行业的发展趋势之一。对于复杂条件下的地下工程(如深基坑),充分考虑工程中的不确定性,结合BIM技术实现建模和工程计算一体化具有重要的工程应用价值。本文基于已有的Revit-FLAC3D接口,结合Revit工程模型和Revit API技术,提出了一种考虑施工精度不确定性的算法程序。利用Revit API对Revit工程模型中施工精度的不确定性进行随机分布,并通过Revit-FLAC3D模型转换接口导入到岩土计算软件中,进行施工精度不确定性分析。结果表明,本文所提出的算法程序能有效进行工程施工精度的不确定性分析。该程序允许对不同施工精度进行分类考虑并建模,简化了计算难度,提高了分析效率。
Using BIM to build a 3 D information model for better utilization of underground space is a promising technique in civil engineering. For deep excavation under complex conditions,it is important to consider the uncertainty of the case with the combination of BIM to achieve the integration of modeling and simulations of the project. In this study, a program is presented based on the existing Revit-FLAC3 D interface while considering the uncertainty of the construction accuracy. Revit API is used to redistribute the uncertainty of construction accuracy randomly in a Revit model.Then the Revit model is imported into FLAC3 D with the conversion interface of Revit-FLAC3 D to conduct the uncertainty analysis. The results show the uncertainty analysis considering construction accuracy is conducted effectively by this program. The program allows the classification and modeling of various construction accuracies, simplifying the calculation of the project and increasing the efficiency of analysis.
