摘要
在分析边坡稳定性评价中,一般都需要对边坡做一个可视化表达,而三维模型是最直观的可视化表达方式。论文就针对某滑坡后的露天矿进行研究,利用低空飞行无人机技术获得边坡影像数据,所得数据经过计算机处理与运算,从而建立边坡三维模型。此方法与传统方法相比,摒弃了传统方法中单点测量、以点带面的不足。运用可视化模型不但能全方位显示边坡整体形态,还能重点突出局部细节,对边坡稳定的测评提供了直观依据。
In slope stability evaluation,it is usually necessary to make a visual expression of the slope,and the 3D model is the most intuitive visual expression.In this paper,a open-pit mine after a landslide is studied,and the slope image data is obtained by low-altitude UAV.The data are then processed and calculated by computer so as to establish 3D modeling of the slope.This method has abandoned the shortcomings of the traditional method concerning single point measurement and point belt.The visualization model can not only show the overall shape of the slope in an all-round way,but also highlight the local details,which provides an intuitive basis for the evaluation of slope stability.
