通过新疆地区低液限粉土路基的室内杠杆承载板法试验,分析了影响土基回弹模量E0的主要因素:压实度K、含水率P、细粒土粉粘粒组成等,并总结回弹模量随这些因素的变化规律及相关关系。先考虑单一因素对于不同土质的土,当含水量为最佳含水量时其压实度与回弹模量之间具有良好的线性关系;当压实度一定时其回弹模量与含水率之间用乘幂函数回归也具有良好的线性关系。结合考虑压实度和含水率来回归分析回弹模量与它们之间的关系,结果与单一考虑时是一致的。并对今后的研究方向提出了建议。

Through indoor test on low liquid limit silt subgrade in Xinjiang area with lever bearing plate, the content p, fine-grained soil powder composition etc. , and the variation of resilient modulus with these factors and their relationship are summarized. First considering a single factor for different soils, when water content is the optimum, there is a good linear relationship between compactness and resilient modulus; when compactness is fixed, there is also a good linear relationship between resilient modulus and water content using power function regression. Then considering both compactness and water content, the relationship between resilient modulus and these two factors is analyzed using regression equation, the result of which is consistent with that when considering a single factor. Therefore, suggestions are put forward for future research.
