| 摘 要： | 为使黄土的湿陷性评价方法更加准确合理,利用改装的应力控制式三轴仪和单向压缩固结仪分别测出三轴试验条件下和单向侧限条件下黄土的自重湿陷系数,并结合湿陷性黄土原位浸水试验的分层沉降数据,研究了不同试验条件下黄土的自重湿陷变形规律及评价方法。研究结果表明：三轴应力条件下黄土的自重湿陷系数曲线拟合的公式可用于计算兰州地区湿陷性...

| Abstract: | To enable evaluation of collapsibility more accurate and reasonable,coefficient of collapsibility under overburden pressure were measured under complex stress condition and lateral restraint conditions by using modified stress control type triaxial collapsible instruments and uniaxial collapsible equipment.Combined with lamination settlement data in situ water immersion test,collapsible deformation and evaluation methods of loess collapsible under over burden pressure at different test conditions were studi... |
