基于三维激光扫描的高陡边坡块体稳定性研究

艰险山区工程建设中高陡边坡块体稳定性是安全与防灾的重要问题，对艰险山区高陡边坡岩体结构面的调查是分析该问题的关键。以澜沧江某重大工程高边坡为研究对象，应用三维激光扫描技术，研究了远距离调查分析岩体结构的分析方法，分析了该高陡边坡的岩体结构面空间分布状况，统计分析了结构面的优势方向和岩石块体的分布状况，以此为基础，应用极限平衡分析方法，研究了该高陡边坡的岩石块体稳定性。

Study on high and steep slope stability Based on 3D laser scanning

Dangerous mountain construction projects block of high and steep slope stability is the important issue of security and disaster prevention, investigation on the surface of the dangerous mountain high and steep slope rock mass structure is the key to the analysis of the problem. The high slope of a major project of the Lancang River, the application of 3D laser scanning technique to study the long-distance survey analysis of rock mass structure analysis method to analyze the distribution of the surface space of the high and steep slope rock mass structure, statistical analysis direction of the advantages of the structure surface and the distribution of rock blocks, as the basis for the application of limit equilibrium analysis method to study the stability of rock blocks of the high and steep slope.
