Abstract: The high and steep slope of loose accumulation body is very unstable and has great potential safety hazard. It is necessary to evaluate the slope stability scientifically and accurately. This paper uses the high precision imaging scanner to scan the high and steep slope of the whole area, at the same time, it accesses a variety of ground slag heap parameters, the evaluation of the slope and the slag heap parameters such as the water catchment area of the area. This paper provides a detailed and accurate data for slope stability analysis, and greatly improvs the efficiency and the accuracy of the evaluation.

Key words: image scanner, 3D scanning, slope stability analysis
