Problems solved by technology

However, this formula only considers the three phases of "solid-liquid-gas", and lacks the consideration of the fourth phase in the unsaturated soil - the matrix suction generated by the shrinkage film on the liquid-gas interface. It is an important characteristic parameter different from saturated soil, which cannot be ignored in the calculation and analysis of unsaturated dam stability

Embodiment Construction

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be described in detail below. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other implementations obtained by persons of ordinary skill in the art without making creative efforts fall within the protection scope of the present invention.

[0037] Due to the late start of domestic tailings dam safety technology, its own independent calculation and analysis system has not yet been formed, and traditional analysis methods of soil mechanics are generally used. Since tailings dams are generally built with earth-rock materials and filtered tailings sand, the dam body is generally in an unsaturated state and belongs to a special type of unsaturated slope. The matrix suction is closely related to the she...

Abstract

The invention relates to an unsaturated tailings dam stability analysis method and system and belongs to the field of tailings dam analysis. The method comprises the steps as follows: S1, acquiring MS (matric suction) of a tailings dam in different unsaturated states; S2, acquiring tailings dam shear strength tau f corresponding to the MS of the tailings dam in the different unsaturated states; S3, analyzing the acquired MS of the tailings dam in the different unsaturated states and the corresponding shear strength tau f by use of a grid Boltzmann model to determine the stability of the unsaturated tailings dam. The MS of the tailings dam in the different unsaturated states and the corresponding shear strength are acquired, the acquired MS of the tailings dam in the different unsaturated states and the corresponding shear strength are analyzed with the grid Boltzmann model, and thus, the stability of the unsaturated tailings dam is determined through the MS of the tailings dam.

Description

technical field [0001] The invention belongs to the field of tailings dam analysis, and in particular relates to an analysis method and analysis system for the stability of an unsaturated tailings dam. Background technique [0002] With the increasing demand for resources in human society, a large amount of tailings will be produced when mineral resources are developed and utilized. As long as tailings are produced in a mine dressing plant, tailings ponds must be built. This is because mine water often It contains a variety of chemicals. If it is not treated, it will cause serious pollution to the surrounding environment of the dressing plant. Properly store the tailings in the tailings pond, and the tailings water will be recycled and recycled after clarification in the pond, which can effectively protect the environment. Therefore, It is said that the tailings pond is an indispensable part of the production of the mine concentrator. [0003] Tailings ponds usually refer t...
