摘要
This paper shows the investigation results of the effect of physical properties of remoulded loess soils on the variation in the matric suction of unsaturated remoulded loess soils via laboratory test. The results show that, for the remolded loess soils, water content, saturation and matric suction at some critical point of the soil water characteristic curves, have closer correlations with dry density than that with particle size distribution. Specifically, both characteristic saturation of transition zone and residual saturation have linear correlation with clay content, while fairly reverse linear correlation with silt content. Saturated water content has linear correlation with silt content, while residual matric suction has reverse linear correlation with it.
