针对施工期的中国锦屏地下实验室二期工程，利用三维激光扫描技术对各个实验室进行持续观测，得到开挖面原始点云数据，并通过一系列数据处理获取实验室轮廓变形、岩体结构及岩体破坏定量化表征信息。实践表明，利用CYCLONE软件处理原始点云数据，能够准确地获取实验室开挖后轮廓随时间的变化，精度满足工程要求，经现场围岩变形破坏特征证实数据处理结果符合实际规律；利用CYCLONE及基于结构面单位法向量的产状算法亦可准确快速地获取结构面产状，测量结果与传统方法结果相符。此外，利用CYCLONE、Geomagic Studio、3DMAX处理原始数据亦为统计实验室围岩破坏程度提供了简便高效的方法，获取的破坏区深度及体积与其他手段测量值基本一致。与点式监测技术相比，基于三维激光扫描的深埋硬岩隧洞监测与数据处理具备同时获取全场变形且快速、安全、高效的优势，对于研究深埋硬岩隧洞岩体力学行为是一种十分有效的技术手段。

In view of the second phase project of the Jinping underground laboratory(CJPL) during construction, in-situ monitoring for each of the deep underground laboratories is conducted by using the 3D laser scanner, in order to obtain point clouds and the information of tunnel contour deformation, rock mass structure, as well as the volume of the rock mass failure by post-processing. Practice has proved that the contours’ temporal change of deep rock tunnels after excavation can be measured after the post-processing of the CYCLONE software; the accuracy of measurement can satisfy engineering requirements. Characteristics of the broken surrounding rock proved that the measurement is consistent with the actual deformation; the orientation of discontinuity can also be measured accurately and efficiently by using the CYCLONE software and the algorithm based on the unit normal vector of the discontinuity; and the results are in good agreement with those obtained by traditional method; and the post-processing of CYCLONE, Geomagic Studio and 3DMAX provides a simple and efficient method to measure the volume, area and depth of the broken rock mass induced by rock burst or collapse; the result of measured depth and volume of rock burst notch is consistent with those obtained by other methods. The measurement based on the 3D laser scanning and data processing in deep rock tunnels has the advantages of simultaneously measuring full-field deformation with fast speed, safety, and high efficiency; it is therefore a quite effective method for conducting research of rock mass behavior in deep rock tunnels.
