Abstract:

Seepage field is a primary factor inducing the seepage instability of tailings dams. Intensifying research on the seepage stability of tailings dams is crucial for ensuring their safety and reducing the risk of dam failure. This paper reviews relevant domestic and international research data from the following perspectives: seepage instability failure types and influencing factors, seepage stability analysis methods, and safety monitoring and early-warning. It points out the existing problems in the research on seepage stability of tailings dams, including the lack of research on seepage failure discrimination techniques, insufficient comprehensive investigations into the factors affecting the seepage field, deficiencies in macro-micro multi-scale model experimental measurement methods and their generalized zoning, and the inadequacy of comprehensive stability analysis and evaluation methods, as well as safety monitoring and early-warning technologies. Given these deficiencies, this paper further clarifies future research priorities and issues requiring in-depth discussion, providing insights for future research.
