Experimental Study on Hydraulic Erosion Characteristics of Ecological Slope of Tailings Reservoir under Rainfall
Rainfall infiltration is the main factor of hydraulic erosion and deformation instability of tailings reservoir slope. Through the hydraulic erosion test of tailings reservoir slope based on rainfall, the parameters of slope internal moisture content, runoff sediment concentration, runoff, start time of surface erosion and gully erosion and slope velocity were tested. The slope protection effect of ecological base material of tailings reservoir slope determined in the previous study was evaluated. The results show that the vegetation allocation model combined with grass, shrub and flower is effective in hydraulic erosion protection of tailings reservoir slope. The critical slope range of ecological slope model of tailings reservoir is 37.5°–42.3° under three kinds of rain intensity. The research results can provide certain theoretical and technical support for the safe operation of tailings reservoir and the development of ecological slope protection theory of tailings reservoir.
