以山西地区的典型黄土试验段为依托,通过现场试验,提出了现场CBR、压实度K、含水量以及现场承载板模量E0之间的相互关系;通过室内试验,研究了不同含水量与不同压实度条件下回弹模量和CBR的变化规律;以含水量和压实度双指标为控制标准,分析现场与室内强度指标之间的相关关系。研究结果表明:室内试验各强度指标之间的相关程度高,现场试验各强度指标之间的相关关系较室内试验结果弱,室内和现场回弹模量存在一定的相关性,室内和现场CBR之间的相关性差。

Taking the typical loess test section in Shanxi region as the basis and depending on field tests, the paper presents the relationship between filed CBR, compactness K, moisture content and on-site bearing plate modulus E0. Through laboratory experiments, the change law of resilient modulus and CBR under different conditions of water content and compactness is studied. The water content and compactness are taken as the control standard to analyze the correlation between field and indoor strength indices. The study result shows that the corelation between the strength indicators from indoor tests is indicators from field tests is weak. The indoor and field resilient modulus strong; however, that between such has certain correlation and the indoor and field CBR has poor correlation.
