三维激光扫描与BIM技术在道路工程质量检验中的应用

Application of 3D Laser Scanning and BIM Technology in Road Engineering Quality Inspection

以某道路工程为例,详细阐述了三维激光扫描技术与BIM技术在道路工程施工质量检验中的应用。借助三维激光扫描技术可非常高效地捕获被测物体表面的三维坐标数据,将该数据进行处理,即可得到能够反映真实现状的道路点云模型。借助BIM技术的参数化建模功能,能够快速得到能够反映设计意图的道路设计BIM模型。将点云模型和设计BIM模型进行模型比对,即可得到现状道路与设计之间的数据偏差。该方法具有可操作性强、检验范围广、测量精度高、分析结果可靠等优点,可降低人力成本、缩短工期,是一种新型的施工质量检验方法。

Taking a road project as an example,expounds the application of three-dimensional laser scanning technology and BIM Technology in road construction quality inspection.With the help of three-dimensional laser scanning technology,the three-dimensional coordinate data of the measured object surface can be captured very efficiently.After processing the data,the road point cloud model which can reflect the real situation can be obtained.With the help of the parametric modeling function of BIM technology,the road design BIM model which can reflect the design intention can be obtained quickly.By comparing the point cloud model with the design BIM model,the data deviation between the current road and the design can be obtained.This method has the advantages of strong operability,wide inspection range,high measurement accuracy and reliable analysis results,which can reduce the labor cost and shorten the construction period.It is a new type of construction quality inspection method.
