摘要
数码摄影测量技术能够克服复杂工程环境对传统地质测绘、编录作业方式的限制,同时又能实现对地形和地质结构面信息的快速采集与编录,在地质工程领域具有广泛的应用前景。依托周宁抽水蓄能电站边坡工程,阐述了该技术所具有的包括现场数据采集、照片合成与精度控制以及成果解译与应用等关键环节在内的工作流程;针对左右岸边坡,建立了含地表影像信息的三维数字化地表模型(DTM),并获得了丰富多样的地质成果数据。研究表明:三维数码摄影测量技术除了能够满足常规的地质编录及其生产性图件的制作等一般性的应用要求以外,还可以将其用于开展相关特定地质数据的采集以辅助开展岩石力学科研,比如结构面表面形态特征专项调查,综合运用数值分析软件进行岩体力学特性描述及其岩体稳定性分析等。
Digital photogrammetry technology can overcome the limitation of complex engineering environment compared with traditional technology of geological mapping and cataloguing,and realize the rapid collection and cataloguing of topographic and geological structural plane information.It has broad application prospects in the field of geological engineering.Based on the slope engineering of Zhouning Pumped Storage Power Station,the workflow of this technology was expounded,including the key issues of field data acquisition,photo photomontage and accuracy control,interpretation and application of the results.A three-dimensional Digital Terrain Model(DTM)with surface image information was established for the left and right bank slope respectively,and various geological data was obtained.In addition to meeting the general application requirements of conventional geological cataloguing and production drawings,the technology can also be used as a supplementary tool for rock mechanics research by collecting relevant specific geological data,such as investigation on surface morphological characteristics of structural planes,and rock mechanics research such as description of rock mass mechanical properties and stability analysis by using numerical analysis software synthetically.
