三维激光技术在危岩体地质信息采集中的应用

摘要

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.%Due to the fracture cutting and dissolution,local knife rocks is evolved into single dangerous rock masses in Wansheng district Chongqing city.Under the storm conditions,the knife rocks are in unstable state.The scale and structure surface characteristics can not be accurately obtained by traditional measurement methods.In this paper,the high-density point cloud data of dangerous rock mass is obtained by the three-dimensional laser scanning technology.So then,the occurrence and geometric information of rock mass discontinuities of dangerous rock masses are extracted.The engineering examples show that the technique has strong applicability and reliability,and it can provide reference for the investigation of dangerous rock mass.
