Abstract

Abstract: Due to the limitation of the topography of Xiaodae tailings pond， the height of the starter dam is 72.5m and increases very fast (the average rate was 18.5m/a). To ensure its safety， the stability analysis was carried out through physical model tests， numerical simulation and theoretical analysis after primary design of the tailings pond. The structural composition of tailings dam， the variation rules of seepage field with or without drainage system in the dam， and the stability of tailings dam under different working conditions were obtained. Results could be helpful to the design and safety management of the tailings pond. So far， the dam has been stably utilized for over five years.

Key words: tailings dam, stability analysis, physical model test, numerical simulation, phreatic surface
