针对晋南地区湿陷性黄土进行压缩试验以及湿陷试验,研究压缩模量随饱和度变化的规律以及湿陷系数增量随压缩模量的变化规律.结果表明:原状黄土及重塑黄土的压缩模量均随饱和度的增大而减小;原状黄土及重塑黄土的湿陷系数均随含水量的增大而减小;原状黄土的湿陷性小于重塑黄土;对于选定压力区间,湿陷系数增量均随压缩模量的增大而增大.
According to the compression test and collapsible test of collapsible loess in Jinnan area, the variation law of compressive modulus with saturation and the increment of collapsibility coefficient with compressive modulus were studied. The results show that the undisturbed loess and remolded loess The compressive modulus decreases with the increase of saturation; the collapsibility coefficient of undisturbed loess and remolded loess decreases with the increase of water content; the collapsibility of undisturbed loess is less than that of remolded loess; for the selected pressure The interval and collapsibility coefficient increase with the increase of compressive modulus.
