【摘要】 针对黄土结构性与湿陷性相关性研究还不够完善的问题,采用晋南地区湿陷性黄土进行压缩试验以及湿陷试验,主要研究湿陷系数随结构性参数的变化规律。结果表明:黄土结构性随竖向压力增大及含水量的提高而变弱;竖向压力为200 k Pa时,湿陷系数最大;黄土结构性是造成其湿陷性的重要原因,结构性越大,湿陷系数相应也越大。更多还原

【Abstract】 In view of the fact that researches are still not perfect for the correlation of loess structure and collapse. Tests are carried out for the collapsible loess of Southern Shanxi to study the collapsible coefficient changes with the structural parameters. The results show that the loess structure becomes weak with the increase of pressure and water. When the pressure is 200 k Pa,the collapsible coefficient is the maximum. The loess structure has direct impacts on the collapsibility. The greater the structural parameters,the greater the collapsible coefficient.更多还原
