ABSTRACT

Geotextile tubes are one of the emerging and promising technologies that help build fine-grain tailings dam. In this study, static stability tests are conducted to evaluate the effect of the geotextile tubes on the tailings dam. The test results indicate that the geotextile has a very significant effect on the stability of the dam body. The failure mode of the tailings dam with geotextile tubes is the interlayer sliding failure between the geotextile tubes. The fracture surface is deepened to a certain extent compared with the tailings dam without geotextile tubes. The failure pressure is larger and the displacement is smaller than that of the tailing dam without geotextile tubes. The displacement and deformation values of the tailings dam with large geotextile tubes are smaller than that of the tailings dam with small geotextile tubes under the same conditions. The stability of the tailings dam with geotextile tubes is better than that of a tailings dam without geotextile tubes.
