渗流影响下尾矿坝稳定性研究

Stability study of seepage under the influence of tailings dam

以磨石沟尾矿库现状坝体为研究对象,采用勘察、试验以及数值模拟手段,研究了尾矿坝正常运行和洪水运行两种不同水位工况下的坝体渗流稳定性及抗滑稳定性,结果表明:现状库内水位正常运行和最高洪水位运行两种工况下的坝体抗滑稳定性安全系数均大于规程所规定的最小安全系数,满足规范要求。

To stone ditch present situation of tailings dam as the research object, the survey, experiment and numerical simulation method, the normal operation of tailings dam and flood run two different water level under the operation condition of dam body seepage stability and stability a- gainst sliding. The results show that normal operation of water level of the status quo of the rolls and the highest flood level run two kinds of work-ing conditions of dam body stability safety factor against sliding are the minimum safety factor is greater than the procedures as stipulated.
