Soil structural stability is fundamentally linked to soil functionality and sustainable productivity. Rheological properties describe the deformation flow behavior of under external stress, playing a crucial role in understanding structure stability. Despite their importance, studies about rheological black soils Northeast China remain limited. This study aims assess two kinds with different degrees degradation China. The parameters these various water contents shearing were quantified by conducting Amplitude Sweep Tests (ASTs) Rotational (RSTs). Both AST RST results showed that as content shear rate increased, strength, viscosity, hysteresis area all decreased Keshan Binxian soils. increase reduces friction between particles, leading decrease Additionally, viscosity content, making it more flowable exhibiting shear-thinning behavior. exhibited stronger recovery strength compared soil; this mainly due higher organic matter soil, which could bonding particles at micro-level. These findings enhance our based on via rheometer.
