摘要
基于高陡岩质边坡三维数字高程实景模型(DEM),从而获取高陡边坡岩体露头结构面三维坐标数据,并利用解析几何理论,得到识别和解译岩体结构面(岩体节理)的倾向、倾角、结构面间距、节理迹线中点面密度和平均迹长等几何信息的解析方法;通过一处高陡岩质边坡的实例应用分析,对该解析方法的可靠性进行验证。该解析方法为高陡岩体结构面几何信息智能识别、精确获取可提供一定的理论基础。
Based on the 3D digital elevation model(DEM)of high-steep rock slope,this paper obtains the 3D coordinate data of outcrop structural plane of high-steep rock slope,and by using the analytic geometry theory,derives an analytical method to identify and interpret the geometric information(inclination,dip angle,structural plane spacing,midpoint density and average trace length)of rock structural plane(rock joint).The reliability of the analytical method is verified by the application analysis of high-steep rock slope.The analytical method provides a theoretical basis for intelligent identification and accurate acquisition of geometric information of high-steep rock slope rock mass structural plane.
