Problems solved by technology

[0003] However, the existing technical solutions can only perform steady-state seepage numerical simulations for the two water points of the highest flood level and the normal water level, and cannot carry out the two transient states from the normal water level to the highest flood level, and then from the highest flood level to the normal water level. The calculation of the seepage field cannot obtain the instantaneous change process of the seepage field of the tailings dam and the influence of the instantaneous seepage pressure on the stability of the tailings dam

Abstract

The invention relates to a method and a device for simulating a seepage field of a tailing dam. The simulation method comprises the steps of providing tailing dam parameters of a target tailing dam; determining a flood hydrograph of the target tailing dam according to the tailing dam parameters; determining a flood regulation reservoir capacity curve of the target tailing dam according to the tailing dam parameters; determining a flood discharge capacity curve of the target tailing dam according to the tailing dam parameters; determining a flood discharge hydrograph according to the flood hydrograph, the flood regulation reservoir capacity curve and the flood discharge capability curve; determining a flood level hydrograph according to the flood discharge hydrograph, the flood hydrograph and the flood regulation reservoir capacity curve; and taking the tailing dam flood level hydrograph as a water level boundary condition for numerical simulation of the tailing dam so as to determine the transient influence of the change of the flood level on the seepage field of the tailing dam in the flood process.

Description

technical field [0001] The present disclosure relates to the technical field of tailings dams, in particular, to a simulation method and device for seepage field of tailings dams. Background technique [0002] Tailings pond is a place where dams are built to intercept valleys or enclosures, and are used to store metal and non-metal mines for ore sorting and then discharge tailings or other industrial waste. Tailings ponds generally use wet discharge and upstream damming, and a certain amount of clear water will generally be formed at the tail of the reservoir area. More importantly, the upstream generally has a large water catchment area. If no corresponding treatment measures are adopted, the reservoir will The catchment water in the area and upstream enters the reservoir area, which shortens the sedimentary beach of the tailings pond and raises the water level in the reservoir area. In severe cases, it will cause seepage damage to the tailings dam, floods and other acciden...
