【摘要】 针对孟家冲尾矿库坝面出现的渗水现象,对坝体的渗流以及稳定进行计算分析。计算结果表明,由于堆积坝的不断升高,导致坝体浸润线抬高,安全稳定系数降低,从而将造成坝体失稳,出现溃坝事故。为消除隐患,提出采用辐射井排渗的设计方案,并对该方案的可行性进行计算分析。更多还原

【Abstract】 Aimed at the seepage phenomenon of Mengjiachong tailings dam of Shougang,an analysis and calculation was made on the seepage and stability of this dam.The result indicated that,due to the continual rising of the stacking dam,the saturation line also rose and the safety stability coefficient decreased,which would cause the instability and break of the dam.In order to eliminate such hidden hazards,a drainage method using radiation wells was presented and the feasibility of this method was verified.更多还原
