Based on the unascertained measure theory, ten influencing factors, including hydrological and engineering geological conditions, slope height, slope gradient, foundation pit depth, drainage facilities, adjacent loads, distance from adjacent loads to the pit edge, maximum daily rainfall, support method and construction method, were selected. The weight of each indicator was determined by using the entropy weight method, and an unascertained measure theory model for a certain foundation pit slope was established. Then the slope's stability level was determined by adopting Euclidean distance discriminant method. The results indicate that when there is heavy rainfall and both drainage facilities and support methods are poor, the foundation pit slope is instable. When there is no rainfall and both drainage facilities and support schemes are good, the slope is relatively stable. It is shown that drainage facilities and support schemes have a significant impact on slope stability. Field monitoring data show that the evaluation results are consistent with the actual situation, demonstrating high reliability of the proposed unascertained measure theory and Euclidean distance discriminant method for evaluating foundation pit slope stability.
