马钢凹山总尾矿库抗震稳定性能研究
|
摘要
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。
Seismic stability of Aoshan tailings dam were investigated by means of Seed-Lee-Idriss analysis procedure,steady state theory and Newmark sliding method based on analyzing the law of tailings deposition,as well as the physicomechanical characteristics of the dam body.The analytic results showed that the liquefaction and dissipation of earthquake-induced pore pressure would not trigger flow failure of the dams under design earthquake shakings.The permanent deformation of the dams was estimated to be less than 20 cm.
