Abstract:Abstract: Due to restriction of surrounding terrain and environment, the slope of tailings embankment designed by the traditional method is too slow. It would greatly reduce the effective capacity of the hillside tailings pond. This paper takes a tailings pond project as an example and attempts to apply the concept of reinforced soil in geotechnical engineering to the design of tailings embankment. This measure is designed in order to increase the pile height and storage capacity of tailings pond. In this paper, GEO-studio professional software is used to simulate and analyze the effect of geotextile reinforcement on the slope of tailings embankment. The results show that the slope ratio of tailings embankment after geotextile reinforced is significantly improved from 1:4.5 to 1:2.5. The effective storage capacity of the tailings pond increased 38%. The research results can provide reference for the design of hillside tailings embankment.
