摘要
为了解决传统方法测量岩体结构信息时存在的工作效率低、危险系数高且精度稳定性差的问题,对基于Sirovision的隧道岩体信息测量方法进行了研究。通过量化分析和对比试验,对测量环境和数据采集环节进行分析,研究了在复杂环境下,隧道围岩三维建模的误差来源,并提出了相应的控制点位置确定、测量点标识、加密点拼接的修正方法。采用修正后的测量方法,对滨莱高速工程姚家峪隧道进行了隧道岩体信息采集和稳定性分析,并取得了良好的效果。研究成果可为致力于将摄影测量技术应用于隧道安全施工和支护参数优化方面的技术人员参考。
In view of the low efficiency,high risk factor,and poor accuracy of traditional methods in measuring the structural information of rock mass,a method for measuring the information of tunnel rock mass based on Sirovision was studied.Through quantitative analysis and comparative experiments,the environment factors and work process of measurement were analyzed,and the sources in 3D modeling errors of tunnel surrounding rock under complex tunnel environment were studied.Moreover,corresponding correction methods,such as determining control positions,marking measurement points,and matching photogrammetric points were proposed.The proposed method was applied to the information acquisition and stability analysis of the tunnel rock mass in Yaojiayu tunnel of Binzhou-Laiwu high-speed project,and good results were obtained.The proposed method could be taken as reference for researchers when applying photogrammetry technology to tunnel’s safe construction and support parameter optimization.
