摘　　要：本文对山西赵家墕干法尾矿赤泥堆场进行静力试验和动三轴试验,得到赤泥材料的基本物理力学参数和邓肯-张本构模型参数,为赤泥堆场动力稳定分析提供了基础数据。采用时程分析法对赤泥堆场的动力稳定进行模拟,对非线性静力条件、动力反应、永久变形和动安全系数进行了计算,并分析了其变化规律。结果表明该干法赤泥堆场坝顶动力放大系数最大值为1.89,永久变形最大值为0.50m,均处于合理范围之内,该赤泥堆场稳定。Shanxi Zhaojiayan Dry Tailing red mud disposal site undergoes static test and dynamic triaxial test in the paper,the basic physical and mechanical parameters of red mud materials as well as Duncan-Zhang Constitutive Model parameters are obtained,thereby providing basic data for the dynamic stability analysis of red mud disposal site.Time history analysis is used for simulating the dynamic stability of the red mud disposal site,and the nonlinear static conditions,dynamic response,permanent deformation and dynamic safety coefficient are calculated.The change laws are analyzed.The results show that the maximum dynamic amplification coefficient is 1.89 and the maximum permanent deformation is 0.50m at the dam top of the dry red mud disposal site,they are within a reasonable range,and the red mud disposal site is stable.
