激光点云在滑塌式危岩体稳定性评价方面的应用

Application of Laser Point Cloud in Stability Evaluation of Collapse Dangerous Rock Mass

在开展危岩体稳定性分析工作时,有部分参数需要进行实地量测来获取。由于危岩体通常所处位置特殊,作业员人面临较大的安全风险,并且所量取的数值一般不够全面,精确度也有限。近年来三维激光扫描技术发展迅速,已经成为获取空间尺度信息的有效手段。本文结合重庆市某危岩体稳定性评估的具体案例,基于三维激光点云量取关键信息,进而辅助滑塌式危岩体稳定性评价,取得了良好的应用效果。

In the process of stability analysis of dangerous rock mass,some parameters need to be measured in field to obtain.Owing to the special location of dangerous rock mass,operators are faced with greater safety risks,and the measured values are generally not comprehensive enough,and the accuracy is limited.In recent years,three-dimensional laser scanning technology has developed rapidly,and has become an effective means to obtain spatial scale information.In this paper,combined with a specific case of stability evaluation of a dangerous rock mass in Chongqing,based on the three-dimensional laser point cloud,the key information is obtained,and then the stability evaluation of sliding dangerous rock mass is assisted,and good application results are obtained.
