Abstract: For water conservancy and hydropower projects, the stability of slope is a common issue, worthy of further study. Because the calculation parameters cannot be accurately chosen, the complex natural and man factors that affect slope stability cannot be fully considered, the widely used mechanical calculation methods, such as limit equilibrium method, have certain limitations. In this paper, various uncertain factors affecting the slope stability are analyzed. Based on the monitoring data, fuzzy comprehensive evaluation method is used to evaluate the treatment effect of slope behind first powerhouse of Huaguangtan hydropower station. The results show that the slope stability has been improved obviously after the treatment, and the expected effect has been achieved.

Key words: monitoring data, fuzzy mathematics, treatment effect, comprehensive evaluation
