Rock Mass Slope Stability Analysis Based on 3D Terrestrial Laser Scanning
Traditional methods for rock mass characterization and field measurements for slope stability analysis include scanline surveying, cell mapping and geologic structure mapping. However, these field methods are time-consuming, hazardous and prone to errors. This paper describes a new method by which 3D Point Cloud Data obtained by laser scanning can be used to model and determine the rock mass discontinuity properties in an automated way with high detail, high accuracy, and no human bias. The automated procedures can also be used to increase the amount of rock mass discontinuity information collected in a field survey. Also, by scanning rock faces from a distance, both safety and access problems are eliminated. This presentation also describes the algorithm and processing technique of 3D laser scan data for slope stability analysis and various geo-engineering applications.
