中文摘要：

利用GDS振动三轴仪进行吕梁压实黄土的动三轴试验研究，探讨了含水率、干密度和加载频率等因素对压实黄土动强度的影响规律．结果表明：压实黄土的动强度随振次的增加而减小，其关系可用对数方程拟合；压实黄土的动强度及动强度参数均随含水率的增大而减小，随干密度和加载频率的增大而增大；动粘聚力和动内摩擦角随振次的增加而减小，并最终趋于稳定．

英文摘要：

A series of dynamic triaxial tests were performed with GDS dynamic triaxial apparatus to study the dynamic strength characteristics of Liiliang compacted loess under moisture content, dry density and loading frequency. The results indicated that the dynamic strength of compacted loess decreased with the increasing vibration times, which could be fitted with logarithmic equation. The dynamic strength and its parameters of compacted loess decreased with the increasing of moisture content and increased with the increasing of dry density and loading frequency. Dynamic cohesive force and dynamic internal friction angle decreased with the increasing of vibration times and finally tended to be stable.
