在剖析尾矿沉积规律和坝体物理力学特征的基础上,采用等价黏弹性理论、稳态强度理论和Newmark滑动变形分析理论,研究了马钢凹山总尾矿库的地震加速度反应、尾矿液化、坝体稳定和变形。计算分析结果表明,凹山总尾矿库可抵御0.1 g地震的袭击,在设计地震荷载作用下,坝体不会出现液化流滑破坏,地震产生的永久变形小于20 cm。 Based on the analysis of tailings deposition and the physical and mechanical characteristics of the dam, the equivalent viscoelasticity theory, steady-state strength theory and Newmark sliding deformation analysis theory are used to study the seismic acceleration response of the total tailings dam in the Maanshan Iron Mountain. Mine liquefaction, dam stability and deformation. The calculation and analysis results show that the total tailings dam can withstand the attack of 0.1 g earthquake. Under the action of the designed seismic load, the liquefied and slip-flow damage of the dam will not occur. The permanent deformation caused by the earthquake is less than 20 cm.
