选取吕梁地区黄土,通过静压压实制备三轴试样,在GDS振动三轴仪上研究含水率、干密度和加载频率对压实黄土动强度的影响规律。结果表明:压实黄土的动强度及动强度参数均随振次的增加而减小,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,动强度与振次之间的关系可用对数方程进行拟合。研究对黄土地区填方区基础建设具有重要意义。
The loess in Luliang region was selected and the triaxial specimens were prepared by hydrostatic compaction. The influence of moisture content, dry density and loading frequency on the dynamic strength of compacted loess was studied by GDS vibration triaxial apparatus. The results show that the dynamic and dynamic strength parameters of compacted loess decrease with the increase of vibration frequency, decrease with the increase of water content, increase with the increase of dry density and loading frequency. The dynamic strength and vibration The relationship between times can be logarithmically fitted. The research is of great significance to the infrastructures of reclaimed land in the loess area.
