摘　　要：基于物元可拓理论,将含水率与变形速率考虑到边坡稳定状态的评价指标中,以便考虑更多的影响因素,建立稳定性评价模型,使边坡稳定性评价结果更加可靠。然后结合工程实例进行了边坡稳定性评价,由计算结果得出边坡稳定性等级为二级,属于较为稳定状态,与实际检测结果一致。因此,该物元可拓理论将为边坡稳定性评价提供新的手段,为滑坡预警和安全生产提供更加科学的依据。Based on matter element and extension theory, moisture content and deiormatlon rate are eonslOerea as the slope stability evaluation indexes. The model of slope stability evaluation is established, which considers the varied factors affecting slope stability. It makes the results of slope stability evaluation more reliable. Combined with the data of mining slope, typical profiles of slope stability are evaluated, suggesting the slope stability belongs to secondary level. The result is accordant with the practical situation. Therefore, the matter element and extension theory can he used in evaluation of slope stability and provide basis for landslide forecast warning and safety production.
