砂土地基CBR值的剪切波速分析模型实验研究
|
摘要
在国内外文献及相关研究的基础上,通过室内实验进一步研究承载比(CBR)与砂性地基土剪切波速之间的规律,建立了砂性地基土CBR值的剪切波速分析模型,并应用于粘土和粉土地基中,实践证明:该模型在不破损道面的前提下获取砂土地基的CBR值,减少了评估费用。
Based on the related research of literature at home and abroad,through the indoor experiment further research on the role of bearing ratio(CBR) and sand foundation soil shear wave velocity,established the shear wave velocity analysis model of sand foundation soil CBR value,and applied to clay and silty soil foundation,the practice proved that: in promise of not damaged pavement this model got sand foundation CBR value,reduced the assessment cost.
