摘　　要：该文通过采用CSS-200钻孔式三维激光扫描仪,对隧道勘察过程中钻孔揭示的覆盖型岩溶空穴进行孔内三维激光扫描测量,获取三维点云数据并建立地下溶洞的三维立体模型。查明了溶洞空穴内部的真实形态和溶洞水平发育特征,为路线方案优化和隧道工程处治措施提供了准确依据。该仪器在公路工程大型溶洞空穴勘察中取得了良好的应用效果。In this paper,the CSS-200 borehole 3 D laser scanner is used to measure the covered karst cavitation which is revealed by drilling in the process of tunnel investigation. The three-dimensional point cloud data is obtained,and the three-dimensional model of underground karst cavitation is built. The true form and horizontal development characteristics of karst cavitation are find out. It provides accurate according for optimizing route scheme and the treatment measures of tunnel engineering. The instrument achieves good application effect in the hole investigation of large karst cavitation of highway engineering.
