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. The dynamic and triaxial tests of Luliang compacted loess were carried out by using GDS vibration triaxial apparatus, and the influence of moisture content, dry density and loading frequency on the dynamic strength of compacted loess was discussed.The results show that the dynamic strength of compacted loess The relationship between them can be fitted by the logarithmic equation. The dynamic and dynamic strength parameters of compacted loess decrease with the increase of moisture content, and increase with the increase of dry density and loading frequency ; Dynamic cohesion and dynamic friction angle decreases with the increase of vibration frequency, and eventually tends to be stable.
