摘要
鞍钢矿业公司风水沟尾矿坝是由初期坝和尾矿堆积坝组成,目前坝高已达65.0 m,其稳定性直接影响到该坝体继续加高的可能性.为此,基于鞍钢矿业公司风水沟尾矿坝工程地质勘测资料,经过对实测主轴剖面的合理性概化和延伸,建立坝体渗流场数值模型,采用有限单元法对该尾矿坝坝体渗流场进行了数值分析,得出了正常工作状态下的坝体渗流规律,并以此对坝体渗流稳定性作出了评价,结果表明,在正常工作状态下该尾矿坝渗流稳定,不会产生如管涌、流土等渗流破坏.
Fengshuigou tailing dam of Angang mining company, which is now 65.0 m high, is composed of starter dam and embankment, for which the stability will affect its feasibility for adding height. Therefore, based on the engineering geology investigation report about Fengshuigou tailing dam of Angang mining company, in text numerical model of seepage flow field is established by properly generalizing measured profile and extending. Numerical analysis of seepage flow field of tailing dam is proceeded used the finite element method, so it can conclude seepage rule of the tailing dam under the normal condition, in the meanwhile seepage stability of tailing dam is evaluated. Result is that the tailing dam is stable for seepage flow, and seepage failure such as piping and drift sand cannot occur.
