摘要
在６０种尾矿坝剖面计算的基础上，得出了坝面加速度放大系数、坝内土中剪应力折减系数的简化计算法，结合Ｈ．Ｂ．Ｓｅｅｄ等的现场上动力强度确定方法，对大石河尾矿坝地震液化进行了简化判别。
In this paper,the two-dimensions seismic response analysis for tailings dam has been carried out by means of sixty combinations.The simplified calculatical procuedure of acceleration amplification coefficient on beach and the recommened value of the shear stress deduction coefficient insite soil are presented.Based on above results and H.B.Seed's method for in-site soil dynamic strength.the liquefaction evaluation of Dashihe tailings dam is done.
