摘　　要：本文介绍振冲法加固尾矿坝的试验研究和应用情况,探讨了工艺、孔距对加密效果的影响,给出了可行的孔距范围。在对大量测试数据分析的基础上,认为惯用的标贯击数判定砂土密实度的标准,应用于均匀的粉砂类尾矿偏于保守,并推荐了适宜的判定标准。This paper presents the test research and application of vibroflotation method being used on the tailings dam's slope, studying and analyzing the effect of the construction technology and borehole interval on the dense result, and a workable range of borehole interval is given. Based on the analysis on a large test da- ta, current standard of SPT method to test the soil density is on the safety side under a condition of homogeneous. Silty sands and a more reasonable standard is presented.
