Fuzzy Comprehensive Evaluation of Open-Pit Slope Stability

According to the stability of open-pit slope, the main influence factors of the slope stability is analyzed firstly. Then, based on the basic principle and method of fuzzy mathematics, the slope stability analysis of fuzzy and comprehensive evaluation further more model is established and the grading index of the slope stability is determined. Finally, by analyzing an example of large open-pit mine slope engineering, the stability of the slope is evaluated. The results show that the evaluation model could consider the uncertain properties in actual slope problems,and the evaluation result is reasonable.
