摘　　要：文章根据含砾钢渣的不均匀系数与曲率系数对钢渣的粒组含量做了重新分配,并根据公路规范控制试样的密实度为30%、50%、70%进行砂砾的击实试验展开进一步研究,含砾钢渣在密实条件下的抗液化性优于疏松和中密状态。通过等幅循环荷载下不排水振动三轴试验的研究方法的试验结果表明,含砾钢渣在不同级配下液化特性不同,试样中的d50对含砾钢渣试样的抗液化特性有较大影响,K(固结应力比)在相同密实度下的同组含砾钢渣的动强度影响为正比例增长。In this paper, the grain group content of steel slag was redistributed according to coefficient of uniformity and coefficient of curvature of steel slag containing gravel, and the compaction tests of gravel were carried out for further study according to the highway code with controlling the densities of the samples to30%, 50%, 70%. The result showed that the liquefaction resistance of steel slag containing gravel under dense condition was superior to that of loose and medium-dense state. The experimental results of triaxial tests under undrained vibration by equal cyclic loading showed that the liquefaction characteristics of steel slag containing gravel under different gradation were different, the d50 in the sample had a significant effect on the liquefaction resistance of the steel slag sample containing gravel, and the influence of consolidation stress ratio K on the dynamic strength of the same group of slag containing gravel in the same density was growing at a positive rate.
