本文介绍了对不同含水率湿陷性黄土进行的一系列高压固结试验结果。变形增量和含水率欧米伽曲线表明，变形量随含水率的增加而增大。在Delta-omega曲线上存在一个突变上升阶段，变形对这一阶段的水分增加非常敏感。最后，提出了考虑含水率增加时湿陷性黄土地基沉降计算的两个经验公式。
This paper shows the results of a serious of high-pressure consolidation tests on the collapse loess samples with various moisture contents. The deformation delta and moisture content omega curves show that the deformation increases with the moisture content increasing. There is an abrupt rising stage in the delta - omega curve, and the deformation appears much sensitive to the moisture increasing this stage. Finally, two empirical formulae are put forwards to calculate settlement of collapse loess foundation by considering the moisture content increasing.
