摘要: 以甘肃某电厂工程为依托,对厂区的黄土地层的工程地质条件进行分析,共采集1700余个黄土样品,进行了常规、颗分、湿陷性等试验,得出该地区黄土性质变化的规律及湿陷系数与物理力学指标间的关系。并从土工试验的物理指标参数入手,采用回归分析对厂区的黄土湿陷性进行评价,得出了黄土各物理指标参数与湿陷系数之间的关系以及本厂区湿陷系数的经验公式,可供分析湿陷强烈程度以及进行试验数据与成果验证的参考。

Abstract: The empirical relationship between the collapse index and the index properties as well as the characteristics of the collapsible loess soils from, Gansu are presented in this paper. The geological conditions of the collapsible loess soil underneath the site are studied. Both conventional geotechnical laboratory tests and the collapse potential tests are performed. Based on the analysis of 1,700 disturbed and undisturbed soil samples collected form an electricity power generation plant, the properties of the collapsible soils are statistically analyzed.
