中文摘要：岩体结构特征控制着岩体力学性质并影响岩体工程稳定性,因此岩体结构地质编录一直是岩体工程地质中的重要内容。针对露天矿山边坡,传统的岩体结构编录方法具有危险性大、效率低等缺点,需要引入新技术实现地质编录的安全、高效。随着近年来无人机的民用化,采用无人机倾斜摄影技术改进传统露天矿坡的地质编录工作将成为未来的发展趋势。本文以浙江某露天采石场矿坡为例,阐述了无人机摄影技术在地质编录中的应用方法和工作流程。基于无人机倾斜摄影技术,采用运动恢复结构法将点云数据转化为岩体三维数字模型,并利用点云的坐标信息实现对岩体结构面产状的解译。通过对比罗盘测量的产状和点云计算的产状验证了该技术应用的可靠性。在此基础上划分了结构面的优势产状,为分析矿山边坡稳定性提供了基础数据支持。

外文摘要：The rock mass structure controls the stability of the rock mass. Therefore,the geological cataloging of rock mass structure has always been an important part of rock mass engineering geology. The conventional method of cataloging the surface structure of open pit mines has the disadvantages of high risk and low efficiency. It is necessary to introduce new technologies to achieve safe and efficient geological cataloging. With the development of drones in recent years,the photos taken with the UAV-equipped camera can be used in the Structure-from-Motion to restore the 3 D structure of the rock mass with the point cloud. The coordinate information of the point cloud can be used to achieve the interpretation of the occurrence of rock mass structure. Taking an open-pit mine slope in Zhejiang as an example,this paper expounds the application method and workflow of UAV photography technology in geological cataloging,and verifies the reliability of the application by comparing the occurrence of compass measurement and the occurrence of point cloud computing. It also divides the dominant occurrence of the structural plane and provides basic data support for analyzing the slope stability.
