激光扫描在阿尔塔什右岸高边坡稳定性分析中的应用

摘要

The right bank of Aertashi Hydro Project is high and steep, the stability of dangerous rocks of the high slope becames one of the main geological problems of the project. Because of the high and steep slope, the artificial geological record could not be undertaken. In order to solve this problem, the digital photography mapping with 3-d laser scanning is conducted to the high slope, and combined with the existing data of the dam safety, and the horizental hole and flat surface geological surveying and mapping data, and using the existing stability analysis method for high-steep slope, a comprehensive analysis is made, and the good effect is obtained, therefor providing references for similar projects.%阿尔塔什水利枢纽工程右岸边坡高陡,高边坡危岩稳定问题成为该工程的主要地质问题之一.由于边坡高陡,无法进行人工地质编录,为了解决此问题,对高边坡进行了三维激光扫描数字摄影成图[1],并结合现有的坝区平硐及地表地质测绘资料、采用已有的高边坡稳定性分析方法进行综合分析,取得良好的效果,供同行参考.
