Abstract: This article analysis one gangue-dam’s anti-slide stability coefficient affected by dam hightening, soakage string character, running conditions of the drainage systen and lens decreaseing. The gangue-dam’s anti-slide stability coefficient decreaseing with the dam hightening, but the amplitude doesn’t as hard as the soakage string’s which is influenced by the running conditions of the drainage system. Lens decreaseing under some certain rules can simplify the section map and decrease the analysis complexity, it can also reflect the engineering geological prospecting, although the result might be a little conservatism. Imitate statics method can not fit for all the gangue-dam anti-slide stability analysis, even though more windage may appear in the result.

Key words: gangue dam, anti-slide, stability, drainage, lens, imitate statics method
