基于BIM技术的土方量计算

Application of Earthwork Calculation Based on Building Information Modeling Technology

提出了基于Auto Desk Revit的土方量计算方法,介绍了BIM技术在土方量计算上的具体应用。该方法利用Auto Desk Revit建立土方量原始表面与设计表面的精确地形模型,通过计算模型体积差值来实现填挖土方量的计算。该方法与常规计算方法相比,可减少人力,降低人为错误的发生,计算精度较高,而且便于修改调整。

The earthwork calculation is present based on Auto Desk Revit,and specific application of earthwork calculation is introduced based on BIM,which can set up the accurate topographical models for original surface of earthwork and design surface of earthwork. According to the calculation of model volume difference value,the calculation of fill and dig earthwork will be solved. Compared with common method,this calculation method can reduce manual Labour and the occurrence of human errors,and have high accuracy and is easy to modify and adjust.
