摘要
为有效进行高边坡施工过程中不利工况的施工检算及动态反馈,以二次开发为依托,提出了基于参数化建筑信息模型(building information modeling,BIM)及有限元方法快速进行高边坡不同工况稳定性检算的整套方案,并通过实际工程案例进行验证。首先,采用Revit二次开发技术实现不利工况高精度正向反馈至BIM模型;其次,将该BIM模型导入ABAQUS中进行快速检算,基于ABAQUS二次开发将有限元计算结果的自定义结构化输出;最后,采用Mesh重构方法将快速检算的结果向BIM环境反馈。结果表明:所提方案实现了数字孪生体与施工现场之间的同步关联,并且实现了数值计算结果与BIM环境互通。可见,BIM技术通过开发后可真实高效反映施工情况,并作为中间枢纽实现施工检算与成果管理,可为相关施工检算及BIM应用提供新思路。
In order to effectively carry out the construction checking calculation and dynamic feedback of unfavorable working conditions in the construction process of high slope,based on the secondary development,a complete set of schemes for fast checking calculation of stability of high slope under different working conditions based on parametric building information modeling(BIM)and finite element method was proposed,which were verified by actual engineering cases.Firstly,Revit secondary development technology was used to achieve high accuracy positive feedback to the BIM model for unfavorable working conditions.Secondly,the BIM model was imported into ABAQUS for rapid calculation,and the finite element calculation results were customized and structured for output based on ABAQUS secondary development.Finally,the mesh reconstruction method was used to feedback the rapid calculation results to the BIM environment.The results show that the proposed scheme realizes the synchronous correlation between the digital twin and the construction site,and realizes the interconnection between the numerical calculation results and the BIM environment.It can be seen that the BIM technology,after being developed,can truly and efficiently reflect the construction situation,and as an intermediate hub,it can realize construction checking and results management,which can provide new ideas for relevant construction checking calculation and BIM application.
