摘要
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.
Targeting the Jinnan collapsible loess, this paper studied the compress modulus changes with the saturation and the increment of collapsibility coefficient changes with the compress modulus. The results of the study show that the compress modulus decreases with the saturation increases for intact loess and remolded loess. The collapsibility coefficient decreases with the water increasing for intact loess and remolded loess. The collapsibility of remolded loess is greater than intact loess. The increment of collapsible coefficient increases with the compress modulus increasing for the selected pressure interval.
