针对当前隧道围岩结构面信息获取方法难以满足隧道快速施工需求的问题,进行基于数字摄影测量系统——CAE Sirovision获取岩体结构面几何信息的研究,详细介绍了双目立体摄影测量的基本原理及结构面产状提取方法。针对具体工程,采用全站仪空间前方交会法进行控制测量,以尼康D7000数码摄像机为摄影工具,采用CAE Sirovision系统进行物像关系模型构建; 通过交互式操作方式实现结构面识别及提取,以测线法RQD指标获取方法为基础,针对传统RQD指标仅能反映隧道轴向结构特性的局限,构建隧道径向RQD评价体系; 针对岩体结构空间差异性,提出隧道径向RQD玫瑰花图,实现了结构面获取、RQD分析、RQD直观显示的集成化处理,为隧道数字化施工提供理论和技术支撑。

The existing information collecting method for tunnel surrounding rock discontinuity can not meet the rapid construction requirements of tunnel. As a result, CAE Sirovision system based on digital photogrammetry is studied; and the basic working principle of the system and the identification method of surrounding rock discontinuity attitude are introduced. In a case study, the total station is adopted for control measuring; Nikon D7000 is used and the model of relationship between images and objects is established based on CAE Sirovision system. The identification and interpretation of digital information of surrounding rock discontinuity can be realized by interactive operation. The rock quality designation (RQD) evaluation system is established. The RQD roseshaped diagram of surrounding rock discontinuity surface is proposed according to spatial difference of rock structure. The results can provide references for digitalized construction of tunnel.
