摘要
通过对CBR试验原理和CBR值影响因素的分析得知,土的粒径大小和土的矿物成分对CBR指标有显著影响,将60多组试验数据的CBR值和液限值进行了统计分析,得出了CBR值满足规范要求液限范围,为指导施工提供了依据。
By analyzing the test mechanism and influenced factors of CBR,the paper proved that soil particle size and mineral composition had significant effect on CBR index,and concluded that CBR value satisfied liquid limit range required by standard for reference.
