Problems solved by technology

Siltation is a ubiquitous phenomenon in porous media. Many scholars have conducted research on silting and found that silting will reduce the permeability of porous media. In tailings dams, the deposition and retention of fine particles or changes in the chemical environment during seepage It will cause silting of the pore seepage channel in th

Description

technical field [0001] The invention relates to a tailings dam silting phenomenon simulation device, which belongs to the technical field of mine geotechnical engineering. Background technique [0002] With the occurrence of tailings pond dam break accidents, more and more scientists and researchers are involved in the research on the mechanism of tailings pond dam collapse in order to achieve the purpose of effectively preventing and controlling tailings pond disasters. Among them, the research on tailings pond The change of the internal structure of the dam body before the dam failure is one of the important research links. [0003] The research on the stability of tailings dam involves the interdisciplinary fields of soil mechanics, hydraulics and sediment dynamics, which brings difficulties to the study of tailings dam stability, and the instability of tailings dam is not caused by a certain factor , is often the result of the joint action of multiple factors. In essenc...
