The Slope Stability Evaluation of Open-pit Mine Based on GIS

摘要

The various influence factors of the slope stability is analyzed on the slope stability problems. Based on the basic principle and method of fuzzy mathematics and GIS, the slope stability analysis of fuzzy and comprehensive evaluation model is established and the grading index of the slope stability is determined. By analyzing an example of large open-pit mine slope engineering, the district stability of this slope is evaluated. The results suggest this evaluation model can evaluate the regional slope stability, and the evaluation result is reasonable.
