摘要
针对江西赣南地区特有的红土原状土和重塑饱和土进行次固结室内试验研究,探讨了该土样的次固结特性,总结得出了e～lgt及e～lgp曲线;通过曲线计算了在不同加荷比下的次固结系数,且对原状土与重塑饱和土的次固结系数进行了比较分析,另外还对加水自由膨胀试验进行了分析。
The secondary consolidation tests have been conducted for the undisturbed soil and remodeling saturated soil which is a special soil in the Jiangxi Gannan area.The secondary consolidation characteristics have been discussed and the e-lgt and the e-lgp curves are obtained.The coefficients of secondary consolidation have been calculated through the curvimeter under different loading ratio.The secondary consolidation parameters have been compared between the undisturbed soil and remodeling saturated soil.In addition,the watering free expansion experiments for two kinds of soil bodies have been analyzed.
