| 摘 要： | 在应用数字近景摄影测量进行岩体结构面几何信息快速获取时，需要在岩体上布设一定数量的控制点，但特殊区域岩体（隧道、硐室、采石场）的结构面相对破碎、特征点极不明显，并且受施工进度的影响，无法在岩体上布设控制点。针对这一问题，本文应用自行设计的活动控制架，在控制架上布设28个控制点，将控制架和岩体结构面一起摄影，然后在VZ（VirtuoZo）工作站上进行内业解译，获取岩体结构面上特征点的空间坐标，再依据所给产状公式获取结构面信息。以净月二采石场岩体边坡为研究对象，进行了活动控制架安装与检验、外业数据采集与内业数据处理等工作；同时基于误差理论点位精度评定方法，对解译的控制点坐标与岩体结构面产状（倾向、倾角）同实测值对比并进行精度分析。结果表明，该方法测量的岩体结构面产状中误差：m倾向=±4°，m倾角=±3°，满足岩体结构面精度测量要求。

| Abstract: | In the application of digital close-range photogrammetry, a certain number of control points should be set up to quickly obtain the geometric information of rock mass discontinuities;however the rock structure surface in a special area (tunnel, chamber, and quarry) is relatively fragmented, the characteristic points are extremely insignificant. Under the influence of construction schedule, the control points cannot be placed. To solve this problem, a self-designed portable controller framework was used, on which 28 control points were placed, and the rock mass discontinuities were photographed and interpreted by using VZ workstation to determine the spatial coordinates of the feature points. After this the information of structural planes was obtained according to the given formula. Taking the rock slope of Jingyue No.2 Quarry as the research object, the portable controller frame was installed and inspected, the collection of the external data and the processing of the internal data were carried out. Through point accuracy evaluation based on error theory, the control point coordinates of interpretation and the orientation of rock mass discontinuity were compared with the measured and the accuracy was analyzed. The results show that this method is feasible,and it opens up a new way to rapidly obtain the geometric information of rock mass discontinuities in special areas where it is inconvenient to place control points. |
