摘　　要：为了提高隧道工程检测效果，分析了三维激光扫描技术在隧道工程检测中的应用，首先采用三维激光成像扫描仪对隧道进行现场踏勘，制定采集方案，采集点云数据之后需要进行数据缩减、点云拼接、去燥等，最后通过获得的数据构建隧道三维模型，最后结合扫描仪获得的数据进行分水岭冲毁面积计算，结果表明该技术的具有一定的实际应用价值。In order to improve the detection effect of tunnel engineering, the application of three-dimensional laser scanning technology in tunnel engineering is analyzed. Firstly, a three-dimensional laser imaging scanner is used to survey the tunnel site. After the collection plan is made, the point cloud data needs to be collected after data collection, point cloud splicing, and desiccation. The tunnel 3D model is constructed from the obtained data. Finally, the watershed erosion area is calculated based on the data obtained from the scanner. The results show that the technology Has a certain practical value.
