| 摘 要： | 以陇东地区黄土为研究对象,探讨了湿陷系数与各种物理指标的内在联系,采用多因素回归分析建立了湿陷系数与含水量、孔隙比、塑性指数(粘粒含量)的分析模型,结果显示湿陷系数与物理指标间具有良好的相关性,采用物理指标计算的湿陷总量与实验测试总量较为接近,计算结果更好的反映湿陷性随取样深度变化的规律,对评价湿陷性黄土地基具有工程实用价值。

| Abstract: | Based on the study of loess collapsible mechanism,the interactions of the loess collapsibility and physical properties in Eastern Gansu Province,P.R.China are analyzed.The correlation equation between collapsible coefficient and water content,porosity,plasticity index(clay content)is developed with multifactor regression.The results show that collapsible coefficient correlated physical index better and the collapsible amounts calculated by the correlation equation are near to the test amount.It rightly reflects collapsible law changed with depth.This equation has a good value in engineering to estimate collapsible loess site. |
