在裂隙切割和溶蚀作用下,重庆市万盛区刀子岩局部形成单个危岩体,在暴雨条件下,刀子岩处于失稳状态,传统的测量方法难以精确得到危岩体的规模和结构面特征。该文采用三维激光扫描技术获取危岩体的高密度点云数据,从而提取危岩体的岩体结构面的产状和几何信息。工程实例表明,该技术具有较强的适用性和可靠性,可为危岩体的调查提供参考。
Under the action of fissure cutting and erosion, a single dangerous rock mass is locally formed in the knife rock of Wansheng district in Chongqing. Under heavy rainfall, the knife rock is in a state of instability. It is difficult to accurately obtain the size and structural plane characteristics of the dangerous rock mass by the traditional measuring methods . In this paper, three-dimensional laser scanning technology is used to obtain the high-density point cloud data of dangerous rock mass, so as to extract the occurrence and geometry information of rock mass structural plane of dangerous rock mass. The engineering example shows that this technique has strong applicability and reliability and can provide a reference for the investigation of dangerous rock mass.
