abstract="Considering that stability of tailing dam is affected by many factors which contain unascertained information, a comprehensive stability evaluation model is proposed based on factor space. Firstly, factor space for comprehensive evaluation was constructed, and unascertained mathematical theory was introduced to establish a factor space-unascertained measurement model. Then, variable combined weights were assigned to influencing factors, and dimensionality reduction of factor space was accomplished through factor synthesis. Finally, with a tailing dam as an example, its stability was evaluated by using confidence criterion, and feasibility and applicability of proposed model were verified. The research shows that evaluation results of this model are consistent with that of field survey, and moreover risk degree ranking of influencing factors is accomplished, which can not only improve evaluation accuracy, but also provide reference for scientific stability evaluation of tailing dam. © 2019 China Safety Science Journal.
