摘要
通过某上游法尾矿坝抗滑稳定性分析,对比分析了坝体加高、浸润线条件、排渗系统运行状况和透镜体简化对尾矿坝抗滑稳定性的影响。结果表明,该尾矿坝抗滑稳定性随坝体的加高而降低;排渗系统运行状况对尾矿坝抗滑稳定性的影响超过坝体加高对尾矿坝抗滑稳定性的影响;根据一定简化原则减少透镜体,从而简化剖面形状和计算复杂程度,是一种能反映工程实际但比较保守的分析方法;拟静力法并非适合于所有的尾矿堆积坝抗震稳定性分析,即便采用其所得结果也可能会出现较大偏差。
This article analysis one gangue-dam's anti-slide stability coefficient affected by dam heightening, soakage string character, running conditions of the drainage system and lens decreasing. The gangue-dam's anti-slide stability coefficient decreasing 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 decreasing 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.
