摘要
在研究高尾矿坝的抗震性能基础上,提出了考虑高尾矿坝—地基相互作用的地震反应分析计算模型,并建立了尾矿单元的物理模型。介绍了其动力平衡方程的建立和求解方法,通过对武钢大冶铁矿白雉山尾矿坝的地震反应分析,考虑高尾矿坝—地基相互作用,坝体动位移增大15%~20%,坝体的动应力增加10%左右。
Based on the study of earthquake proof character of high tailing dam, a calculation model for seismic response analysis considering the interaction between high tailing dam and its foundation was proposed, and a physical model of tailing was developed. The formation and solution method of their dynamic equilibrium were introduced, through seismic response analysis of Baizhishan tailing dam in Daye iron mine of Wuhan I & S Co., considering the interaction between high tailing dam and foundation, the dynamic displacement of dam body is increased by 15%~20%, and the dynamic stress of the dam body is increased by about 10%.
