| 摘 要： | 黄土的湿陷性为黄土的主要工程地质问题 ,本文通过对黄土的物性指标进行主成分分析 ,得出 1个在总方差中占的比例最大的综合指标Y1,然后对综合指标Y1和自重湿陷系数δzs进行非线性回归 ,进而确定黄土湿陷性与物性关系。

| Abstract: | The collapsibility of loess is the major engineering problem for loessic strata. Through analysis of essential constituents of physical property indices of loess, an aggregative index, Y1, is found, which takes up the maximal proportion in total variance therefore represents the physical property indices of loess. Then the nonlinear regression analysis is made for Y1 and δzs, coefficient of self weight collapsibility, therefore, the relation between the collapsibility of loess and its physical property is determined. |
