Study on the Influence of Elevation of Tailing Dam on Stability

Abstract: Abstract. This paper takes Yunnan as the object of a tailing, by theoretical analysis and numerical calculation method of the effect of seismic load effect of elevation on the stability of the tailing, to analyse the stability of two point driven safety factor and liquefaction area. The Bishop method is adopted to simplify the calculation of dynamic safety factor and liquefaction area analysis using comparison method of shear stress to analyse liquefaction, so we obtained the influence of elevation on the stab… Show more

“…The liquefaction of tailing sand often occurs under earthquake which has a negative effect on the stability of the dam. The discriminant method of seismic liquefaction is obtained by considering several different working conditions and analysing the results of two-dimensional seismic response analysis of tailing dam [30]. Based on the relationship between the anti-liquefaction degree and the pore pressure ratio, a simplified calculation formula for the excess pore pressure on the tailings dam is proposed [31], the calculation indicates that the area near the water's edge of the upstream slope is the easiest area to liquefy, followed by the initial dam.…”
