摘要:

岩体质量分级是判断岩体质量好坏,保障矿山工程安全和合理开展的重要基础工作。采用立体成像技术,从岩体图像信息分析和三维点云信息识别出发,通过分析点云空间三维信息得到了岩体的结构面分布情况,基于岩体表面图像信息分析得到了节理形态、风化程度等信息;提出了基于RMR法的节理岩体质量快速分级方法,并结合节理岩体实例进行了应用可行性探讨。该方法能够为岩体质量分级初步的快速判别和应用提供参考。

Abstract:

Rock mass quality grading is important basic work to judge the rock mass quality and guarantee safe and reasonable mine engineering.Stereoimaging technology is used,the rock mass image information is analyzed and 3D point cloud information is recognized.The rock mass structural face distribution is obtained by analyzing point cloud spatial 3D information.Based on rock mass surface image information analysis,the joint morphology and weather-ing conditions are obtained.The joint rock mass quality rapid grading method is proposed based on RMR,whose feasibility has been discussed in the case study of joint rock mass.The method can provide reference for preliminary rapid judgment and application of rock mass quality grading.
