基于水土交互作用分析的尾矿坝渗流场研究

尾矿坝的渗流稳定对结构稳定有重要影响，渗流场分析是尾矿坝工程研究的重要内容。渗流与水土作用密切相关，将水土作用理论引入尾矿坝渗流场分析中，运用地球化学、力学及相关理论，结合尾矿的结构特点，从宏观和微观两方面探讨尾矿坝内水土交互作用，将其概括为水土化学作用、水土物理作用、渗流力学作用分别阐述。并以某铁矿尾矿坝为工程实例进行了有限元渗流模拟，为尾矿坝稳定性分析提供基础原始数据，并进一步为尾矿坝致灾机理提供基础理论参考。

Study on the Seepage Field of Tailing Dam Based on Water-Soil Interaction

The seepage stability of tailing dam is of great importance to the dam structure stability and therefore, the analysis of seepage field is an important content of tailing dam engineering research. The theory of water-soil interaction to which seepage is closely related is introduced into the tailing dam seepage analysis. On the basis of the geochemistry and mechanics, and their relative theories, in light of tailing's structural characteristics, the paper discusses, macroscopically and microscopically, the water-soil interaction within tailing dam in terms of water-soil chemical interaction, water-soil physical interaction and seepage mechanical interaction. The seepage field finite element simulation is conducted for a real case of iron ore tailing dam so as to provide the basic primary data for tailing dam stability analysis and also the basic theoretical reference for the study of disaster-causing mechanism of tailing dam.
